Carrier Concentration Analysis in 1.2 kV SiC Schottky Diodes Under Current Crowding
F. Bonet , O. Aviñó-Salvadó , Member, IEEE, M. Vellvehi , X. Jordà , P. Godignon , and X. Perpiñà IEEE Electron Device Letters Die-level current crowding phenomena are analyzed at the microsecond timescale with an internal IR-Laser Deflection set-up. To this end, the 4H-SiC plasmaoptical coefficient for the refractive index...
Local Thermal Resistance Extraction in Monolithic Microwave Integrated Circuits
M. Vellvehi, X. Perpiñà, J. León, O. Aviñó-Salvadó, C. Ferrer and X. Jordà IEEE Transactions on Industrial Electronics The thermal resistance of a High Electron Mobility Transistor (HEMT) forming part of a Monolithic Microwave Integrated Circuit (MMIC) is non-invasively extracted under real working conditions (electrical and thermal) by infrared thermal imaging....
