Published in 2019 at "Applied Physics Letters"

DOI: 10.1063/1.5084190

Abstract: Fabrication of a two- and three-dimensional (2D/3D) heterojunction device has attracted significant attention for developing high performance photodiodes, light emitting diodes, solar cells, and other electronic devices. Here, we reveal the effect of ultraviolet (UV)… read more here.

DOI: 10.1364/oe.26.005408

Abstract: In this work, we explore the possibility of using hybrid graphene/GaN phototransistors to get high responsivity, high speed, and large photosensitive area. The responsivity of our hybrid graphene/GaN phototransistors with a relatively large 15.2 mm2… read more here.

Published in 2022 at "Optics express"

DOI: 10.1364/oe.460151

Abstract: Versatile applications have driven a desire for dual-band detection that enables seeing objects in multiple wavebands through a single photodetector. In this paper, a concept of using graphene/p-GaN Schottky heterojunction on top of a regular… read more here.
