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 和激光器等半导体器件支撑着现代生活的许多领域，例如通信、消费电子产品和传感。然而，对于频谱的许多重要部分来说，经济高效、实用的来源并不可用。例如，气体传感系统需要使用中红外源，其中通过测量吸收的光量来确定气体浓度。许多重要气体，包括二氧化硫等大气污染物，在这部分光谱中具有最强的特征吸收，因此需要新的传感器来帮助满足日益增长的立法要求。然而，实现这些波长的器件不仅极具挑战性，而且生产起来也很复杂且成本高昂。这导致许多组件制造发生在英国境外，这使英国传感和仪器制造商与海外竞争对手相比处于劣势。该提案旨在通过开发利用石墨烯独特性能的新型设备来彻底改变这些组件的制造。这种二维碳原子片非常坚固、轻，并且是一种非常好的电导体和热导体。这项工作的一部分旨在尝试利用这些特性来开发一种相当于自由电子激光器的固态器件，它将产生没有其他选择的波长的激光源，并且其操作将挑战现有的概念激光操作。最终，基于石墨烯的组件的制造可能比传统的半导体器件更便宜且更可持续。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）的制造，从而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新产品的途径。
