This PhD proposal will use Nottingham University's bespoke facility for the EPItaxial growth and in situ analysis of two dimensional (2D) SEMiconductors (EPI2SEM) to investigate an emerging class of 2D semiconductors based on metal chalcogenides. The aim is to develop fabrication methods to study and optimise prototype tunnel junction devices based on 2D metal chalcogenides heterolayers. For these new systems to meet technological needs, several challenges must beaddressed, from the atomic-scale precision manufacturing and scalability, to integration into devices for exploitation in real applications. The ultimate goal is to develop arrays of nanoscale optical sensors with high sensitivity and operating between the ultraviolet (UV) and the terahertz (THz) bands of the electromagnetic spectrum.

该博士学位建议将使用诺丁汉大学的定制设施进行外延生长和对二维（2D）半导体（EPI2SEM）的原位分析，以研究基于金属辣椒剂的新兴2D半导体类。目的是开发基于2D金属果酱杂质杂层的原型隧道界接线设备来研究和优化原型隧道结的制造方法。对于这些新系统以满足技术需求，必须挑战从原子级的精度制造和可扩展性到集成到实际应用中的设备中进行剥削。最终的目标是开发具有高灵敏度的纳米级光学传感器阵列，并且在紫外线（UV）和电磁频谱的Terahertz（Thz）频段之间运行。
