Hello fellow SpecMat'ers --

Here is a request (actually, two) from a UCSB student, soon to join the lab.

Mary

 

It was very nice meeting you on Monday. I'm still waiting for my PI to 
come back from a talk in order to sign the papers needed to get access 
to the lab as well as the CIS grant. In the meantime I was wondering if 
I could make a couple SpecMat requests.

 

1. Acetone Vapor Clean:

Materials: PMMA coated Silicon samples

Process: A small 50 mL container is filled with approximately 20-30 mL 
of acetone and heated to 80C. The container itself is sealed with the 
exception of a very small, 1-2 mm hole, in the lid to allow for the 
escape of acetone vapor. Samples coated with a PMMA film are placed on 
the hole with the PMMA side down to allow for the removal of PMMA 
without excess capillary forces.

 

2. Carbon Nanofilm Anneal

Material: Graphene on Silicon samples

Process: Silicon pieces with graphene on top are cleaned under an 
atmosphere of hydrogen (4%) in argon at 300-400C to remove residual 
resist or other organic contaminants present on graphene surfaces. Argon 
is needed instead of nitrogen to ensure minimal oxygen in presence of 
and prevent the doping of the graphene samples.

 

Please let me know if any further information is required. Thanks.
