Low-dimensional materials for optoelectronic devices

半导体是计算机、可再生能源发电、显示器、照明和成像传感器的核心，仅举几例。如果我们将这些材料的尺寸减小到原子尺寸，这将极大地改变它们与其他材料的相互作用以及它们对外部刺激（如光、热或电场和磁场）的反应。通过将半导体的电子控制、发光和检测特性与自旋电子学的数据处理和新功能相结合，“自旋工程”半导体器件将能够开发出更高效率的光电子器件，用于可持续能源和照明，以及为移动的设备和物联网开发低功耗计算架构的开放途径。该项目将涉及制造和使用诸如石墨烯、2D半导体和半导体纳米线的低维材料来表征电子和光电器件。为了实现这一目标，我将开发新的器件制造技术和材料生长工艺，以获得新的物理学，并开发具有更高性能或使用更大规模的“散装”材料无法实现的新功能的纳米材料（光）电子器件。

Semiconductors lie at the heart of computers, renewable energy generation, displays, lighting, and imaging sensors, to name but a few. If we reduce the size of these materials to atomic dimensions this dramatically changes how they interact with other materials and how they react to external stimuli such as light, heat or electric and magnetic fields. By combining the electronic control and light emission and detection properties of semiconductors with the data handling and novel functionalities of spintronics, "spin-engineered" semiconductor devices would enable the development of higher efficiency optoelectronic devices for sustainable energy and lighting, as well as open pathways to develop low power computing architectures for mobile devices and the Internet of Things.This project will involve the fabrication and characterisation of electronic and optoelectronic devices using low-dimensional materials, such as graphene, 2D semiconductors and semiconductor nanowires. To achieve this I will develop novel device fabrication techniques and material growth processes to access new physics and develop nanomaterial-based (opto)electronic devices with higher performance or new functionalities unattainable using larger scale "bulk" materials.
