This grant provides accessories that expand the capabilities of a just-delivered Riber 32 MBE machine and to purchase materials-characterization instrumentation. The machine expansion consists of two parts: a thermal treatment unit, resulting in higher purity and higher throughput growth; and effusions cells, power supplies, and controllers to permit dopants to be added. The materials-characterization instruments will be used to study quantitatively the relationship between the presence of dopants and the electrical and optical properties of the MBE-grown materials; to quantify overall crystal quality, to identify dopant and carrier concentration and mobility; and to give carrier type and concentration as a function of materials depth. These instruments will expand our capability to study the basic electronic and nonlinear optical properties of materials, and to fabricate and test all-optical (nonlinear optical) and electro-optic devices for photonics.

该补助金提供附件，扩大能力， 一台刚刚交付的Riber 32 MBE机器， 材料表征仪器。 机器 膨胀由两部分组成：热处理单元， 导致更高的纯度和更高的产量增长;以及 渗出细胞，电源和控制器，以允许 添加的掺杂剂。 材料表征仪器 将被用来定量研究之间的关系， 掺杂剂的存在以及的电学和光学性质 MBE生长的材料;量化整体晶体质量， 确定掺杂剂和载流子浓度和迁移率;以及 给出载流子类型和浓度作为材料的函数 深入 这些仪器将扩大我们的研究能力， 材料的基本电子和非线性光学性质， 制造和测试全光学（非线性光学）， 用于光子学的电光器件。
