This equipment request is for acquisition of a double crystal x-ray spectrometer system that will be used in the evaluation of films and quantum well structures, such that optimum molecular beam epitaxial growth techniques can be developed. At present there is a significant increase of interest in II-VI semiconductors due to recent success in growth of films and multiple quantum well structures of those materials by molecular beam epitaxy. Applications now envisioned include infrared detection, nonlinear optics, blue LED and laser devices, and flat panel electroluminescent displays. The research effort described in this proposal represents a leading program in the study of several aspects of II-VI epitaxy. The proposed research deals with fundamental concepts of heteroepitaxy, the optical and electrical properties of quantum wells, and the general problems of charged-particle transport in these potentially important materials.

这项设备需求是为了获得一套双晶X射线光谱仪系统，该系统将用于薄膜和量子阱结构的评估，以便开发最佳的分子束外延生长技术。目前，由于分子束外延技术在生长薄膜和多量子阱结构方面的成功，人们对II-VI半导体的兴趣大大增加。现在设想的应用包括红外探测、非线性光学、蓝色LED和激光设备以及平板电致发光显示器。这项建议中描述的研究工作代表了在研究II-VI外延的几个方面的领先计划。这项拟议的研究涉及异质外延的基本概念，量子阱的光学和电学性质，以及这些潜在重要材料中带电粒子输运的一般问题。
