摘　　要：氧锌镁(ZnMgO)是由宽禁带半导体材料氧化锌(ZnO)和氧化镁(MgO)构成的三元合金,作为直接带隙宽禁带半导体,其禁带宽度理论上可在ZnO的3.37 eV和MgO的7.8 eV之间连续可调,并且具有纳米结构丰富、制备温度低、抗辐射能力强、稳定性高等特性,是一种优异的紫外光电探测材料。更为有趣的是,除了上述优点外,ZnMgO还具备压电性、热释电性和铁电性等丰富的物理性质,为其紫外探测器的应用拓展提供了新的可能,相关研究也成为近年来紫外探测领域的研究热点。鉴于此,本文全面综述了ZnMgO丰富的材料特性,重点介绍和讨论了能带工程、铁电/热释电/压电极化、低维结构等在其紫外探测器件的结构设计、性能调控和应用发展等方面的研究进展。Zinc magnesium oxide(ZnMgO),a ternary alloy constituted of wide bandgap semiconductor materials zinc oxide(ZnO)and magnesium oxide(MgO).As a direct bandgap semiconductor,theoretically,its bandgap width can be continuously tuned between 3.37 eV of ZnO and 7.8 eV of MgO.It possesses numerous properties such as abundant nanostructures,low preparation temperature,strong radiation resistance,and high stability,making it an excellent detection material for ultraviolet photodetectors.Moreover,apart from the aforementioned advantages,ZnMgO also exhibits rich physical properties such as piezoelectricity,pyroelectricity,and ferroelectricity,which pro⁃vide new possibilities for the expansion of the applications in ultraviolet detectors.Consequently,related research has become a hotspot in the field of ultraviolet detection in recent years.In view of this,this thesis comprehensively reviews the material properties of ZnMgO,focusing on the research progress in bandgap engineering,ferroelectric/py⁃roelectric/piezoelectric polarization,and low-dimensional structures in the structural design,performance regula⁃tion,and application development of its ultraviolet detection devices.
