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.

该博士提案将使用诺丁汉大学定制的二维（2D）半导体（EPI2SEM）外延生长和原位分析设施来研究基于金属硫族化合物的新兴2D半导体。目的是研究和优化基于二维金属硫族化合物异质层的原型隧道结器件的制造方法。为了满足这些新系统的技术需求，必须解决几个挑战，从原子尺度的精密制造和可扩展性，到集成到实际应用中开发的设备中。最终目标是开发具有高灵敏度的纳米级光学传感器阵列，并在电磁波谱的紫外（UV）和太赫兹（THz）波段之间工作。
