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.

半导体是计算机、可再生能源发电、显示器、照明和图像传感器等的核心。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相互作用的方式以及它们对光、热或电场和磁场等外部刺激的反应方式。通过将半导体的电子控制、光发射和检测特性与自旋电子学的数据处理和新颖功能相结合，“自旋工程”半导体器件将能够开发用于可持续能源和照明的更高效率的光电器件，并为开发用于移动设备和物联网的低功耗计算架构开辟道路。该项目将涉及电子和物联网的制造和表征。 使用低维材料的光电器件，例如石墨烯、二维半导体和半导体纳米线。为了实现这一目标，我将开发新颖的器件制造技术和材料生长工艺，以获取新的物理原理，并开发基于纳米材料的（光）电子器件，这些器件具有使用更大规模的“块状”材料无法实现的更高性能或新功能。
