摘要 | An n-type cladding layer structure which has good luminescence properties without the use of substances corresponding to RoHS Directive and a high Cl-doping efficiency, i.e. which facilitates the manufacture of a semiconductor optical element and device with low crystal defects and high reliability, and an active layer and a p-type cladding layer therefor are provided. The n-type layer being lattice matched to an InP substrate and containing Group II-VI compound as a main ingredient is a Group II-VI compound semiconductor, in which the Group II elements consist of Mg, Zn, and Be and the Group VI elements consist of Se and Te. The n-type layer of the present invention is characterized by a large energy gap, high energy of the bottom of a conduction band that is effective for suppressing the Type II luminescence, high carrier concentration, and low crystal defects attributed to a good quality crystallinity. |
其他摘要 | 一种n型包覆层结构,其具有良好的发光性能而不使用符合RoHS指令的物质和高Cl-掺杂效率,即便于制造具有低晶体缺陷和高可靠性的半导体光学元件和器件,以及提供有源层和p型包层。与InP衬底晶格匹配并含有II-VI族化合物作为主要成分的n型层是II-VI族化合物半导体,其中II族元素由Mg,Zn和Be组成,VI族元素由Se和Te组成。本发明的n型层的特征在于具有大的能隙,导带底部的高能量,其有效抑制II型发光,高载流子浓度,以及归因于良好质量结晶度的低晶体缺陷。 |
