The MURI
Compact Pulsed Power Program project, managed by the AFOSR, is
being carried out in collaboration
and consultation with Martin
Gundersen of the University of Southern California (USC).
He is
in
the Departments
of Electrical Engineering-Electrophysics
&Physics and is the head of
the Pulsed Power Group. I
also
interact with his PhD studentsKathy Gu and Qiong
Shui.
They are both students in the Department of Materials Science. Recently, through this collaboration, an
effort on semiconductor switch device simulation has been started.
there.
The basic idea of this effort is to simulate various
device
configurations to theoretically see which one has the best
characteristics
for pulsed power applications. A high hold off voltage
is crucial for this. Doing this simulation study will help to decrease
the number and types of devices which will need to be fabricated for
this purpose. The
fabrication and characterization will also be done at USC. The
devices
which have been considered so far have been FET's and VJFET's
fabricated
from GaAs,
Si,
and 4H-SiC.
