[期刊论文] 作者：XiaohangLi,RussellD.Dupuis,TimWernicke,
来源：PhotonicsResearch 年份：2019
Semiconductor UV photonics research has emerged as one of the most heavily invested areas among semiconductor photonics research due to numerous crucial applications such as sterilization, sensing, curing, and communication. The feature iss......

来源：PhotonicsResearch 年份：2019
We report on AlGaN-based tunnel heterojunctions grown by metalorganic vapor phase epitaxy enabling fully transparent UVC LEDs by eliminating the absorbing p-AlGaN and p-GaN layers. Furthermore, the electrical characteristics can be improved......
Electrical and optical characteristics of highly transparent MOVPE-grown AlGaN-based tunnel heteroju

This paper reports a comprehensive analysis of the origin of the electroluminescence (EL) peaks and of the thermal droop in UV-B AlGaN-based LEDs. By carrying out spectral measurements at several temperatures and currents, (i) we extract in......
Improved performance of UVC-LEDs by combination of high-temperature annealing and epitaxially latera
