Symposium E: III-Nitride, SiC, and Diamond Materials for Electronic Devices

The symposium program includes 13 invited speakers, over 130 contributed papers and a panel discussion. Because of the rapid developments of new research andapplications involving III-N, SiC and Diamond semiconductors, we invitesubmission of Late News Posters for this symposium. These papers should represent significant advances that have not been widely discussed. A very limited number will be accepted and presented.

The accepted Late News Posters will be displayed for a single day at the meeting. Viewing will be during morning and afternoon coffee breaks, and manuscripts will be considered for the proceedings volume.

Abstracts should be prepared following the MRS Format and should be submitted by Email or FAX to Bob Nemanich (see below) prior to February 29. Abstracts will be considered as they are received.
