Engineering Research Equipment Grant: Molecular Beam Epitaxy Upgrade

这是一个升级现有分子束外延（MBE）设施的设备请求。现有的系统（瓦里安360,1980年份）缺乏许多被认为是维持最先进水晶性能所必需的功能。提议的升级包括计算机控制的积液池，快速泵送系统，残余气体分析仪，砷的裂解积液池和掺杂剂的高温池，以及霍尔效应系统的新电子设备。这些改进对于维持我们持续的生产力和确保研究生精通最先进的晶体生长技术是必要的。

This is an equipment request to upgrade an existing Molecular Beam Epitaxy (MBE) Facility. The existing system (Varian 360, 1980 vintage) lacks many of the features that considered necessities to sustain a state of the art crystal capability. The proposed upgrade includes computer controlled effusion cells, a rapid pumping system, residual gas analyzer, cracking effusion cell for arsenic and high temperature cell for dopants, and new electronics for a Hall Effect system. These improvements are necessary to maintain our continued productivity and to be sure that the graduate students are versed in state of the art crystal growth technology.
