基于AlGaN材料的深紫外发光二极管(DUV LED)具有体积小、能耗低、工作电流小、亮度高和发光响应速度快等优点,发光具有很强的杀菌效果,是汞灯的理想替代品,广泛地用于生物研究和污水处理领域。同时也可以为生物实验室、实验用器具及医院手术室、医疗器具等消毒,在微制造技术和环境科学领域也大有可为,而且还可以用于制造侦测有毒粒子的传感器。由于其很容易与晶体管和集成电路配套使用,是近几年来迅速崛起的半导体光电器件。然而由于材料极化特性、器件结构等一系列因素,导致器件的性能难以与同族材料制备的可见光LED比拟,严重阻碍了其产业化进程。针对上述难题,本论文设计构建了系列DUV LED器件结构,并采用APSYS软件,研究了有源区结构、电子阻挡层结构及p型区结构对器件性能的影响机理,并对器件结构进行了优化设计,获得了以下研究成果。(1)深入研究了有源区结构对器件性能的影响,研究发现在一定范围内增加量子阱(QW)和量子阱势垒(QB)层厚度可以提高载流子注入效率和辐射复合效率,提升内部量子效率(IQE)和总功率。然而,超过一定阈值后,由于量子限制stark效应,导致IQE下降。在本工作中,当QW和QB的厚度分别为3.50、10.00 nm时,器件性能最佳。I-V曲线显示,QW和QB厚度的增加,对器件开启电压几乎没有影响。该研究强调了材料组成、能带对齐和厚度在器件性能优化方面的重要性。优化QW和QB层的厚度可以极大地提高内部量子效率(IQE)和LED总功率。(2)探讨了超晶格电子阻挡层(SL-EBL)对AlGaN DUV LED性能的影响。深入研究了SL-EBL厚度对器件功能的影响,揭示了结构参数和LED性能之间微妙的关系。研究表明,SL-EBL厚度的变化对AlGaN DUV LED的效率有重大影响,随着SL-EBL厚度的增加,IQE和总LED功率均呈现出一致的降低。在所有结构中,较薄的SL-EBL厚度为1.00 nm时可实现最佳性能。此外,分析还探讨了SL-EBL结构和不同铝(Al)组分对SL-EBL性能的影响。对带隙能量的检查显示,较大的SL-EBL层导致导带和价带边缘发生显著变化,表明载流子限制增强,载流子迁移性降低。通过优化SL-EBL结构,可以达到更高的IQE,达到68.37%,强调了精心设计和组成在提高LED性能中的重要性。(3)研究探讨了p型层内Al化合物浓度的变化对器件特性的影响。审查了AlGaN DUV LED的Al比例与效率之间的相关性,以及它们各自的厚度。在优化Al浓度之后,确定了7).(6./7).(6.的配置,第一层厚度为10 nm,第二层厚度为10 nm,可以实现72.12%的内部量子效率(IQE)。该配置在注入电流为500 A/m时,还可实现144.24 W/m的输出功率。
