项目摘要

Semiconductor devices such as LEDs and lasers underpin many areas of modern life such as communications, consumer electronics and sensing. However, cost-effective, practical sources are not available for many important parts of the spectrum. For example, mid-infrared sources are required for use in gas sensing systems in which the gas concentration is determined by measuring the amount of light absorbed. Many important gases, including atmospheric pollutants such as sulphur dioxide, have their strongest characteristic absorption in this part of the spectrum and new sensors are needed to help meet increasing legislative requirements. However, it is not only extremely challenging to realise devices at these wavelengths, but it is also complicated and costly to produce them. This has resulted in much component manufacture occurring outside the UK, which puts UK sensing and instrument manufacturers at a disadvantage compared to overseas competitors.This proposal aims to revolutionise the manufacture of these components by developing novel devices that utilise the unique properties of graphene. This two dimensional sheet of carbon atoms is extremely strong, light and has is an extremely good electrical and thermal conductor. Part of this work will be aimed at trying to exploit these properties to develop a solid-state equivalent of a Free Electron Laser, which would create laser sources at wavelengths at which there are no alternatives, and the operation of which would challenge established notions of laser operation. Ultimately, the manufacture of graphene based components could be less expensive and more sustainable than conventional semiconductor devices. In turn this will impact the manufacture of products containing these components such as gas sensors and analysers and therefore provide UK sensor and analyser manufacturers a route to new products by initiating a graphene based component industry.

LED和激光等半导体设备支撑了现代生活的许多领域，例如通信，消费电子和传感。但是，对于频谱的许多重要部分，不可用成本效益的实用来源。例如，在气体传感系统中使用中边缘来源，其中通过测量吸收的光量来确定气体浓度。许多重要的气体，包括大气污染物，例如二氧化硫，在这一部分中具有最强的特征吸收，需要新的传感器来帮助满足日益增长的立法要求。但是，在这些波长上实现设备不仅极具挑战性，而且生产它们也很复杂且昂贵。与海外竞争对手相比，这导致了英国以外的许多组件制造，这使英国的传感和仪器制造商处于劣势。该提案旨在通过开发利用石墨烯独特特性的新型设备来彻底改变这些组件的制造。这二维碳原子非常强，光线非常强，是一个非常好的电气和热导体。这项工作的一部分将旨在试图利用这些属性，以开发出相当于免费电子激光器的固态，该激光器将在没有其他选择的波长下创建激光源，并且其操作将挑战已建立的激光操作概念。最终，与传统的半导体设备相比，基于石墨烯的组件的制造可能更便宜，更可持续。反过来，这将影响包含这些组件的产品（例如气体传感器和分析仪）的生产，因此通过启动基于石墨烯的组件行业为英国传感器和分析仪制造商提供了新产品的途径。
