    • PROBLEM TO BE SOLVED: To reduce the driving voltage of a group III nitride semiconductor light-emitting element.SOLUTION: A p-cladding layer 15 has a superlattice structure where a p-AlGaN layer of 0.5-10 nm thick and an InGaN layer are grown repeatedly and laminated. Growth temperature of the p-AlGaN layer is 800-950°C. When forming the InGaN layer on the p-AlGaN layer, supply of trimethyl aluminum (TMA) is stopped and trimethyl indium (TMI) is supplied while keeping the growth temperature of the p-AlGaN layer thus increasing the supply amount of Ga source gas and forming an InGaN layer having a thickness of 1-2 molecular layers. Since the p-cladding layer 15 can be made thin while keeping excellent crystal quality, the driving voltage can be reduced.
    • 要解决的问题:降低III族氮化物半导体发光元件的驱动电压。 解决方案:p覆层15具有超晶格结构,其中重复地层叠0.5-10nm厚的p-AlGaN层和InGaN层。 p-AlGaN层的生长温度为800-950℃。 当在p-AlGaN层上形成InGaN层时,停止供给三甲基铝(TMA),并提供三甲基铟(TMI),同时保持p-AlGaN层的生长温度,从而增加Ga源气体的供应量, 形成厚度为1-2分子层的InGaN层。 由于可以在保持优异的晶体质量的同时使p型包覆层15变薄,所以能够降低驱动电压。 版权所有(C)2013,JPO&INPIT
