Exciton dynamics in diamond and two-dimensional metal dichalcogenide enabled van der Waals heterostructures

Project Description

Two-dimensional (2D) materials offer a platform that allows the creation of heterostructures with a variety of properties. One- atom-thick crystals now comprise a large family of these materials, collectively covering a comprehensive range of features and numerous intrigue scientific challenges. For instance, the property of CVD synthesised atomically thin 2D materials have strong substrate dependence associated with their epitaxial lattice growth.
Moreover, atomically thin 2D materials can be assembled in vertical stacks that are held together by relatively weak van der Waals forces, enabling coupling between monolayer crystals with incommensurate lattices and arbitrary mutual rotation. In this project, we will fabricate new-type of heterostructures based on incommensurate molybdenum diselenide/disulfide (MoSe2 or MoS2) or tungsten disulfide/diselenide (WS2 or WSe2) monolayers with Diamond, and we will investigate a series intrigue excitonic bands hybridisation, exciton dynamics under radiation, and optoelectronic device studies (phototransistor, photodetectors and LEDs). These findings underpin strategies for band-structure engineering in semiconductor devices based on van der Waals heterostructures grown on Diamond.
