Current injection 1.54 µm light-emitting devices based on Er-doped GaN/AlGaN multiple quantum wells
( OSA - The Optical Society , 2016 , Article)We report on the growth, fabrication and electroluminescence (EL) characteristics of light-emitting diodes (LEDs) based on Er-doped GaN (GaN:Er) and GaN/AlGaN multiple quantum well (MQW:Er) active layers. The LED structures ... -
Zero-/Low-Speed Operation of Multiphase Drive Systems With Modular Multilevel Converters
( Institute of Electrical and Electronics Engineers Inc. , 2019 , Article)Modular multilevel converter (MMC)-based AC motor drives are emerging trend-research. They ease medium-/high-voltage handling in high-power applications with reduced footprint and life-cycle costs. A known challenge ...
