|
The purpose of this experiment is to determined the limiting operating temperature for Beta-SiC. To do so, samples will be heated in sequence
to observe any volatile Si coated on the window. The coating is observed above 1400C for the conventional SiC (mixuture of alpha and beta) and this
coating leads to HV shorting problem. |
