Quantum well infrared photodetectors (QWIPs) have been demonstrated to be a suitable candidate for IR detection applications. These detectors attracted increasing interest due to their design flexibility and broad spectral absorption from short wave

We review the recent progress to achieve air stable III-nitride photocathodes for applications as photon detectors. High conductivity p-type films are critically important to realize high quantum efficiency (QE) photocathodes with effective negative

Here, we report on the application of an electron source with high accelerating voltage (62 kV–200 kV) to simulate betavoltaic power generation capabilities of a planar GaN PIN (p-GaN/i-GaN/n-GaN) device. The in situ electrical characterization rep

Beryllium has been considered a potential alternative to magnesium as a p-type dopant in GaN, but attempts to produce conductive p-GaN:Be have not been successful. Photoluminescence studies have repeatedly shown Be to have an acceptor level shallower

We report on the enhanced incorporation efficiency of magnesium dopants into facets of hexagonal hillock structures in N-polar GaN, studied by comparative analysis of GaN:Mg films grown by MOCVD on high and low hillock density GaN template layers. To
