A Fully Funded 4-year PhD Studentship in Synthesis of Atomically Thin 2D Materials with Tailored Optoelectronic Properties

Imperial College London - Department of Materials, Faculty of Engineering

Campus: South Kensington

Duration: 48 Months

Supervisor: Dr. Cecilia Mattevi

We are seeking applications from enthusiastic graduates for a four-year PhD studentship to study transition metal dichalcogenides in their atomically thin form with the aim to identify synthesis methodologies that can enable control over their opto-electronic properties. The ultimate goal will be to integrate the synthesized material in practical devices. The project will be based in the Department of Materials at the central London Campus of Imperial College.

The discovery of graphene has triggered an enormous interest in 2D atomically materials systems with different properties. Atomically thin semiconducting transition metal dichalcogenides (TMDs) (e.g.WS2, MoS2) display unique optoelectronic properties, which are strongly dependent on their chemical doping and dimensionality. However, synthesis of high quality 2D materials with controlled electronic features is yet to be demonstrated.

The aim of the proposed research is to synthesize atomically thin semiconducting TMDs via chemical vapour deposition with controlled optoelectronic properties to achieve device integration. To accomplish this objective, various synthesis and materials techniques will be used. Examples are: chemical vapour deposition, metal organic chemical vapour deposition, Raman spectroscopy, photoluminescence spectroscopy, atomic force microscopy, and ultraviolet photoemission spectroscopy.

You will work within a team of dynamic PhD Students and Research Associates (www.imperial.ac.uk/two-dimensional-materials), in newly refurbished laboratories on the South Kensington Campus. You will also have extensive interaction with several international collaborators, as well as project partners. You will have access to advanced characterization facilities within the department including Titan 80/300 TEM/STEM and the recently funded ambient pressure photoelectron spectroscopy (APPES).

We are seeking candidates with a minimum 2:1 (or equivalent) first degree in Materials Science, Chemistry or Applied Physics. This 4-year studentship is open for home and EU students; it will begin in October 2017 and will cover rate fees plus the standard maintenance stipend. Applications will be processed as received.

This project will be supervised by Dr Cecilia Mattevi and informal enquiries should be sent to Dr Cecilia Mattevi (c.mattevi@imperial.ac.uk) with two pages CV prior to formal application. For questions regarding the admissions process, please contact Fiona Thomson (fiona.thomson@imperial.ac.uk).

Closing date: (Midnight BST) 26th October

Formal applications can be completed online (only after informal enquiries): www3.imperial.ac.uk/materials/research/phdopportunities while information about the Department can be found at www3.imperial.ac.uk/materials.
