一般說明
氧化镓（III）（Ga2O3）是一种宽带隙半导体，属于透明半导体氧化物（TSO）家族。它可以形成不同的多晶型，如α-、β-、γ-、δ- 和 ε-。多晶和纳米晶 Ga2O3 可以使用多种方法制备，如化学气相沉积、热蒸发和升华、分子束外延、熔体生长等。它被广泛用作各种应用的功能材料，包括光电子、化学传感器、催化、半导体器件、场效应晶体管等。
應用
Ga2O3 被广泛用作制造电致发光器件的主体材料。例如，可以使用掺杂铕的 Ga2O3 薄膜作为发光层来制造光学透明的电致发光器件。
由于其独特的光学和电学特性，如中等电导率和高激光损伤阈值，Ga2O3 可用于激光驱动的电子加速器、低损耗等离子体和硅基电介质激光加速器。
它也可以用作丙烷脱氢制丙烯的有效催化剂。
