Impact Ionization Coefficients in GaN Measured by Above- and Sub-E g Illuminations for p − /n + Junction
Takuya Maeda,Tetsuo Narita,Shinji Yamada,Tetsu Kachi,Tsunenobu Kimoto,Masahiro Horita,Jun Suda +6 more
TL;DR: In this article, a method to extract impact ionization coefficients of electrons and holes using above and sub-bandgap illuminations for a p−/n+ junction diode was proposed.
Journal ArticleDOI
Impact ionization coefficients of 4H-SiC in a wide temperature range
TL;DR: In this article, the temperature dependence of impact ionization coefficients of electrons and holes along 4H-SiC photodiodes was determined in a wide temperature range from 156 K to 561 K.
Proceedings ArticleDOI
Ultrahigh-voltage SiC devices for future power infrastructure
TL;DR: By utilizing high-purity and thick SiC epilayers and appropriate junction termination structures, ultrahigh-voltage blocking over 20 kV has been achieved in SiC PiN diodes and transistors.
Journal ArticleDOI
Chemical vapor deposition and deep level analyses of 4H-SiC(112̄0)
TL;DR: In this paper, an x-ray diffraction analysis has revealed that a lattice-mismatch strain between n− epilayers and n+ substrates could be minimized by introducing n-type buffer layers.
