MRSEC Seminar Series with Dr. Len Feldman

*********************************
There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Summaries

Summary Sentence: This talk will describe the work of our team (see below) in characterizing and modifying the interface to raise the mobility by a factor of ~100 in the last 10 years. The current mobility values, although adequate for commercial devices, remain below

Full Summary:  Our first MRSEC Seminar of the Spring Semester welcomes Dr. Len Feldman, from the  Institute for Advanced Materials, Devices and Nanotechnology, Rutgers University on Tuesday, February 11, 2014 at 3:00pm in the Marcus Nanotechnology Building, First Floor Event space.  His talk is titled: Structure and composition of the 4H-SiC surface and dielectric interface

Abstract: The 4H polytype of silicon carbide (SiC) is a promising candidate for high temperature and high power metal-oxide-semiconductor device applications. It is also used in the formation of graphene on SiC. In such applications high quality surfaces and interfaces are critical. For power MOSFETs the limit to application has been the dielectric/SiC interface which gives rise to a low inversion layer mobility. This is in sharp contrast to Si/SiO2 interfaces. This talk will describe the work of our team (see below) in characterizing and modifying the interface to raise the mobility by a factor of ~100 in the last 10 years. The current mobility values, although adequate for commercial devices, remain below expectation and require further research.

Co-workers: Auburn University-J. Williams, S. Dhar; Rutgers MEIS Group-T. Gustafsson, Can Xu, S. Shubeita, H. Lee; Rutgers Chemistry-E. Garfunkel, Yi Xu
