Explicit gain equations for hybrid graphene-quantum-dot photodetectors
Kaixiang Chen, Chufan Zhang, Xiaoxian Zang +3
Graphene is an attractive material for broadband photodetection but suffers from weak light absorption. Coating graphene with quantum dots can significantly enhance light absorptio…
Explicit Gain Equations for Single Crystalline Photoconductors
Jiajing He, Kaixiang Chen, Chulin Huang +3
Photoconductors based on semiconducting thin films, nanowires and 2-dimensional atomic layers have been extensively investigated. But there is no explicit photogain equation that a…
A photoconductor intrinsically has no gain
Yaping Dan, Xingyan Zhao, Kaixiang Chen +1
In the past 50 years, the high gain in quantum efficiency of photoconductors is often explained by a widely accepted theory in which the photogain is proportional to the minority c…
Self-aligned process for forming microlenses at the tips of vertical silicon nanowires by atomic layer deposition
Yaping Dan, Kaixiang Chen, Kenneth B. Crozier
The microlens is a key enabling technology in optoelectronics, permitting light to be efficiently coupled to and from devices such as image sensors and light-emitting diodes. Their…
