TU Students Earn Prestigious Publication

Friday, January 07, 2011

TU Physics students Yingdi Liu (MS 2010), Michael Halfmoon (BS
2010, MS 2012), and Christine Rittenhouse (BS 2011), along with
their research advisor Professor Sanwu Wang, published an article
titled “Passivation Effects of Fluorine and Hydrogen at
the SiC-SiO2 Interface” in the December 13, 2010 issue of Applied
Physics Letters
.

The paper reports their quantum-mechanical investigations
concerning defect passivation of high-temperature and high-power
microelectronics based on silicon carbide (SiC). Their results
suggest a new way to reduce the density of the interface traps - by
incorporating fluorine in the form of molecules and hydrogen in the
form of atoms. The reduction of the interface trap density is
necessary for effective applications of SiC microelectronics.  

Applied Physics Letters, published by the American Institute of
Physics
, is widely regarded as a leading journal in the field of
physics and especially applied physics. According to the journal’s
web site, Applied Physics Letters publishes “reports on significant
new findings in applied physics.”
