Photodetectors: Overview of Ga2O3-Based Photodetectors

Abstract

This chapter provides an overview of Ga2O3-based photodetectors, which have been the subject of many published papers. I classify and summarize these detectors in several tables, roughly according to the device types: film-based photodetectors (photoconductors, metal-semiconductor-metal photodetectors, and alloy-film-based photodetectors), vertical Schottky photodiodes that use bulk single crystals, heterojunction photodetectors, and nanostructure-based photodetectors. In each class of detectors, some interesting devices are spotlighted.
