Abstract: Gallium nitride based light-emitting diodes (LEDs) are presently fundamentally transforming the lighting industry, but limitations in the materials and fabrication methods of LEDs introduce substantial challenges to their future development. Among the remaining key bottlenecks… read more here.

Abstract: Current crowding is the main bottleneck preventing the prosperity of AlGaN-based deep-ultraviolet light-emitting-diodes (DUV-LEDs) considering the low electrical conductivity of p-type contact layer. A deeper understanding of the current distribution in p-AlGaN is critical, which… read more here.

DOI: 10.1109/ted.2017.2782705
Abstract: This paper investigates the influences of various topside cell structures of insulated gate bipolar transistor (IGBT) on the current crowding effect during high current turn-OFF by symmetrical multicell numerical simulations. It is observed that lower… read more here.
