Current State of Ga2O3-Based Electronic and Optoelectronic Devices. Brief Review

In this review, we consider the main gallium oxide areas of application in electronics and optoelectronics with focus on power electronics devices (rectifiers, field effect transistors), solar-blind photodetectors, luminescent devices, gas sensors, spintronic and memory devices.As an introduction, we provide the valuable data on the basic physical properties of the existing Ga 2 O 3 polymorphic modifications.We discuss device design based on various gallium oxide crystalline forms including those exploring Ga 2 O 3 single crystals, thick layers, thin films, nanostructures, and Ga 2 O 3 -based heterostructures.Then, the information on the parameters and characteristics of electronic and optoelectronic devices based on gallium oxide is presented.In addition, recently emerging and requiring additional research Ga 2 O 3 application fields such as photocatalysis and thermomechanical actuating, are briefly addressed.
