Support for the EPSRC National Centre for III-V Technologies at Sheffield

国家中心为英国大学提供广泛的先进半导体材料，以开展在电信（包括互联网）、发光二极管、激光、移动电话、高频雷达和超高速光电子和电子领域应用的设备和物理研究。这种结构以一系列薄的纳米级层的形式产生，其厚度可以控制在几个原子的范围内。这种结构提供了与它们的小尺寸相关的新的物理效应，使各种设备的发明成为可能，例如用于光纤通信的激光器，精确的药物输送和污染控制。由这些结构制成的其他设备可以为成像系统检测大范围的光学波长，并形成高效的太阳能电池。

The National Centre provides a wide range of advanced semiconductor materials to UK universities in order to carry out research into devices and physics with applications in telecommunications (including the internet), light emitting diodes, lasers, mobile phones, high frequency radar and ultra high speed optoelectronics and electronics. The structures are produced in the form of a series of thin nanoscale layers, the thickness of which can be controlled to within just a few atoms. Such structures offer new physical effects related to their small dimensions which enable the invention of a wide range of devices such as lasers for optical fibre telecommunications, precise drug delivery and pollution control. Other devices made from these structures can detect a wide range of optical wavelengths for imaging systems and form efficient solar cells.
