Industrial funded PhD Studentship – Development of 2D transition metal dichalcogenides through vapour phase deposition 

Optoelectronics Research Centre

Applications are invited for an industrially funded PhD Studentship to be filled as soon as possible. This scholarship will fund students for their tuition fees, a bursary to cover living expenses and a Research Training Support Grant for research consumables and conference attendance. This role will be based at the Optoelectronics Research Centre within the Zepler Institute and will use state-of-the-art facilities at the Southampton Nanofabrication Centre.

Interviews will be held on a rolling basis until the position is filled.

PhD Description: 

Two-dimensional (2D) transition metal dichalcogenides (TMDCs), such as MoS2, WS2, MoSe2 and WSe2, have become promising complementary materials to graphene sharing many of its attributes. They may however offer properties that are unattainable in graphene, in particular TMDCs offer a bandgap tunable through both composition and number of layers. This has led to use of TMDCs in applications such as transistors, photodetectors, electroluminescent and bio-sensing devices. The current challenge in this emerging research field is to provide a reliable process to fabricate large area of atomically thin 2D TMDCs on the desired substrate. 

Vapour phase deposition, such as chemical vapour deposition (CVD)1, Van der Waals Epitaxy (VdWE)2 and atomic layer deposition (ALD)3, has the advantages of offering conformal, scalable, and controllable thin film growth on a variety of different substrates. In this PhD project, we will work closely with Industrial partner to develop these emerging 2D TMDCs materials through novel vapour phase deposition processes with metal organic precursors provided by the Industrial partner. The Company will also provide mentoring, time in their laboratory facilities and team building activities with other PhD students they support.

This project will require a highly interdisciplinary approach, using a wide range of techniques including, thin film deposition processes, materials characterization and device fabrication. Enthusiastic candidates with practical experience in one or more of these disciplines are encouraged to apply and for the successful candidate, tuition in new techniques will be provided.
