WANTED: scraps and samples of B implant in Silicon?

[James Conway]

Hello,

By chance, would anyone have any sized scraps of silicon substrate with
any pattern of an Ion Implant containing B (Boron), or another low Z
metal dopant?

I am seeking a material set or dopant that exhibits little to no
Secondary Electron Contrast in the SEM,  but  would have a decent yield
in Back Scatter Contrast when used in Backscatter Imaging mode.

This would be used to teach BSE imaging in the SEM Practicum Class I
teach, and to assist the San Francisco Police Department Gun Shot
Residue Analysis Laboratory.

Thank you.
