Abstract
Inspired by the success of gallium oxide as a wide bandgap semiconductor, aluminum gallium oxide films which possess higher bandgap values have been researched extensively. Higher bandgap values of AGO films have successfully expanded the potential range of applications. In this review, we thoroughly summarize the recent developments in AGO growth, properties, and applications. Deposition techniques and the influence of synthesis parameters on AGO film are examined. Properties of AGO are influenced by the growth techniques and parameters, which promote the AGO films to be employed in desired applications. Electrical properties, optical properties, and morphological studies are discussed in detail. Finally, summary and future perspectives are identified.
