In the past, these systems have mostly taken the form of bulk solutions. More recently, researchers have integrated bilayers with chip-based architectures to take advantage of advanced optical, scanning probe and electronic characterization. These applications typically involve the creation of hybrid devices with inorganic and bilayer components, both of which affect the final device performance. In particular, the properties of supported lipid bilayers (SLBs) are known to depend on the substrate chemistry and topography as well as the lipid used. In spite of the large body of work involving these systems, there is still much that remains unknown about the formation and ultimate structure of the interface between these very different materials. One outstanding question in the study of SLBs is the role that the bilayer deposition method plays in determining the bilayer properties. In the work I will present, we have developed a new method for forming and patterning lipid bilayers: bubble collapse deposition (BCD). This method is similar to an in situ version of Langmuir-Blodgett deposition, and offers unique possibilities for the fabrication of lipid-based devices. With BCD, we have demonstrated the first SLB formation on alumina using uncharged lipids. We have also used BCD to produce a hybrid lipid-gated chemical delivery device, and to directly transfer lipids from a cell membrane to a substrate surface. I will discuss these applications and the fundamental insights they offer into the interactions between lipids and common semiconductor fabrication materials. -------------- next part -------------- An HTML attachment was scrubbed...

In this talk, I will describe our recent research in this aspect and give two examples enabled by such capability. The first example is the strongly correlated photon transport in nano-photonic waveguides. Photons normally do not directly interact with each other, yet many practical considerations, such as quantum communication and information processing, and other novel optoelectronics devices require the use of entangled photons. I will describe how to deterministically generate and manipulate strong photon-photon interactions via a two-level system. Such strong interactions have profound consequences on the photon transport properties. A deep understanding of the mechanism also provides a key to achieve low power optical switching at single-photon level. It also represents the most fundamental form of nonlinear optics. Moreover, the configuration is well-suited for on-chip all solid-state implementations. In the second part of my talk, I will describe how to design novel metamaterials by exploiting the electromagnetic states at subwavelength scales. In particular, I will discuss the mechanisms and properties of a special class of metamaterials -- broadband, ultra-high refractive index metamaterials. Such artificial structures will be useful in many applications such as subwavelength lithography and imaging, broadband slow-light, and sensitive interferometer. ------------------------- Pizzas would be served ! -------------------------- All are welcome. -- Gaurav Thareja Ph.D candidate, Nishi group Electrical Engineering Stanford University 420 Via Palou Mall, CISX 128 Stanford, CA 94305 Tel: 650-704-1029 Email: gthareja at stanford.edu From mahnaz at stanford.edu Thu Apr 9 09:51:06 2009 From: mahnaz at stanford.edu (Mahnaz Mansourpour) Date: Thu, 09 Apr 2009 09:51:06 -0700 Subject: Microscope yellow filter Message-ID: <49DE277A.2030002@stanford.edu> Hello all, Mario tells me that most yellow filters are missing this morning., he has looked all over for them.

It is therefore a useful method for studying properties of fluorescent objects in supported phospholipid bilayers, a common cell membrane model system. Unfortunately, in its conventional form there are limits on the kinds of systems and questions that can be probed using FLIC. To address this issue, extensions to existing interferometry approaches have been developed to be applicable to a wider range of problems than those than can be investigated with laterally homogeneous supported phospholipid bilayers. One extension takes the form of a new imaging technique that allows the extraction of distance information for fluorescent objects that are not laterally homogeneous. In variable incidence angle fluorescence interference contrast microscopy (VIA-FLIC), a fluorescent sample is assembled above a reflective silicon interface and the incidence angle of excitation light is varied by placing annular photomasks with different radii in the aperture diaphragm plane of the microscope. Constructive and destructive interference occur near the reflective interface, and varying the incidence angle alters the interference pattern, and hence the intensity of detected fluorescence. By collecting a series of images of a single fluorescent object, an intensity profile as a function of angle of incidence can be constructed, and this profile is characteristic of a specific distance between the fluorophore and the interface. A second extension is the development of a model membrane system that can be probed using interferometry techniques, while also positioning the phospholipid bilayer hundreds of nanometers from the substrate surface. This separation distance is sufficient that cell membrane proteins conceivably could be incorporated into this system without the surface interaction problems typically observed for proteins in supported phospholipid bilayers. Although many challenges remain to be addressed, the architecture of this system raises the possibility of studying protein conformational dynamics using fluorescence.

These experiments usually require a single mask (or sometimes no mask at all) and frequent travels to local hardware stores. In spite of their apparent simplicity, the theoretical explanations for some of these experiments are not trivial. In this seminar, I will talk about several such adventures using simple materials and test set ups in areas such as dynamic ferrofluid platforms, vibrating ratchet-shaped microchannels for droplet manipulation, ferropaper actuators, frequency controlled micromotion of soft-bodied cylinders with ratchet-shaped legs, and stretchable electrodes for recording and stimulation. -------------- next part -------------- An HTML attachment was scrubbed...

Krishna Saraswat in Department of Electrical Engineering Date: Thrusday, April 23th, 2009 Time: 1:00pm Location: CISX Auditorium Abstract As silicon MOSFETs are aggressively scaled down to sub-100nm regime, the performance improvement becomes more challenging only by geometrical scaling because of parasitic resistance/capacitance and leakage/power consumption constraint. Mobility enhancement enables performance improvement additively to other scaling parameters so that high mobility channel material is regarded as a promising performance booster. Ge is one of the candidates because of its high electron/hole mobility, process compatibility with Si LSI technology and low temperature process due to low melting point. However, there are several device/process issues to be solved for high performance CMOS with Ge. In this seminar, I will report three achievements contributing to Ge MOS technologies: (1) low interface states GeO2 formed on Ge by radical oxidation for reliable gate stack, (2) Fermi level depinning and contact resistance reduction at metal/Ge contact and (3) uniaxial stress engineering for electron mobility enhancement in Ge NFETs. (1) A number of surface passivation methods have been used for Ge gate stack, however, none of them provides as low interface state density as Si. GeO2 has now been reconsidered as an interfacial layer for high-k/Ge gate stack. In this work, novel radical oxidation method was introduced for interfacial GeO2 growth, which enabled low interface state density in high-k/GeO2/Ge gate stack, 1x1011cm-2V-1. (2) Low contact resistance in metal/n-Ge contact is challenging because Fermi level of metal is strongly pinned near the valence band edge of Ge. Preventing wave function penetration into Ge and reducing the effect of metal induced gap state of Ge are the key to the Fermi level depinning. In this work, we demonstrated Schottky barrier height modulation and contact resistance reduction by inserting thin interfacial layer between the metal and the Ge. (3) According to the bulk mobility, electron mobility enhancement in Ge is only 2x higher over Si, and has to be boosted by stress. In this work, we systematically applied stress to different channel directions and achieved electron mobility enhancment in Ge NFETs. Theoretical simulation and experiments clarified the physical mechanism of electron mobility enhancement by uniaxial stress.

The purpose of doing so is to come to terms with a distinctive kind of research object, as well as to chronicle a significant line of research and technology-development associated with the broader nanoscience/nanotechnology movement. We are calling this kind of object a ?test object?: one of a family of epistemic things that make up the material culture of laboratory science. Depending upon the case, a test object can have variable shadings of practical, mathematical, and epistemic significance. Clear cases of test object have highly regular and reproducible visible properties that can be used for testing instruments and training novices. The test object featured in this paper is the Silicon (111) 7x7, a particular surface configuration (or, as it is often called, a ?reconstruction?) of silicon atoms. Research on this object over a period of several decades was closely bound up with the development of novel instruments for visualizing atomic structures. Despite having no obvious commercial value, the Si(111) 7x7 was a focal object for the formation of research networks in industry and academia. It also exhibited a complex structure that offered a sustained challenge for structural theorists. The study follows shifts in the epistemic status of the Si(111) 7x7, and uses it to re-examine familiar conceptions of representation and observation in the history, philosophy, and social study of science. *Michael Lynch *is a Professor in the Department of Science & Technology Studies at Cornell University. His research is on discourse, visual representation, and practical action in research laboratories, clinical settings, and legal tribunals. His most recent book, *Truth Machine: The Contentious History of DNA Fingerprinting* (University of Chicago Press, co-authored with Simon Cole, Ruth McNally & Kathleen Jordan) examines the interplay between law and science in criminal cases involving DNA evidence. He is Editor of the journal *Social Studies of Science*, and current President of the Society for Social Studies of Science (4S). *Karin Knorr Cetina* is professor of the Theory of Sociology at the Universit?t Konstanz, and the George Wells Beadle Distinguished Service professor of Anthropology, Sociology and of the Social Sciences at the University of Chicago. She specializes in economic anthropology/sociology, the anthropology of science, knowledge and technology, globalization, contemporary social theory, and qualitative methods. She is author of numerous books, chapters, and articles, including *Epistemic Cultures: How the Sciences Make Knowledge* (1999). She recently co-edited *The Sociology of Financial Markets* (2004), with Alex Preda. Currently, she focuses on the study of global microstructures and social studies of finance. *This talk is sponsored by Stanford's Science, Technology, and Society Program.

Tomorrow! Abstract: Transparent conductive electrodes are important components of thin-film solar cells, light-emitting diodes, and many display technologies. Doped metal oxides are commonly used, but their optical transparency is limited for films with a low sheet resistance. Furthermore, they are prone to cracking when deposited on flexible substrates, are costly, and require a high-temperature step for the best performance. We demonstrate solution-processed transparent electrodes consisting of random meshes of metal nanowires that exhibit an optical transparency equivalent to or better than that of metal-oxide thin films for the same sheet resistance. Organic solar cells deposited on these electrodes show a performance equivalent to that of devices based on a conventional metal-oxide transparent electrode.
