An ultra-wide-bandgap semiconductor photodetector for linear measurement of bright sub-bandgap light
Jiahao Dong, Zhenjing Liu, Rafael Jaramillo
Semiconductor photodetectors are conventionally optimized for sensing weak optical signals, and they typically saturate at low-to-moderate light intensity. Here, we demonstrate sub…

High sub-bandgap response and fast switching enabled by thermal quenching in carbon-doped semi-insulating GaN
Jiahao Dong, Auditee Majumder Momo, Austin Fehr +6
Carbon-doped GaN is a promising material for sub-bandgap triggered optical switches. When incorporated in GaN, carbon introduces deep compensating centers that enable defect-mediat…
