PhD in Modelling Electronic Excitations in 2D Materials at Imperial College

Imperial College London - Department of Materials

Department/Faculty: Faculty of Engineering

Duration: 48 Months, starting in October 2018

Supervisors: Dr Johannes Lischner

Applications are invited for a three-year PhD studentship in modelling electronic excitations of two-dimensional materials at Imperial College London starting.

We live in the silicon age as this material is the basis of many technologies, such as computers, cell phones or solar cells. Since the discovery of graphene in 2004, two-dimensional materials were regarded as potential replacements of silicon that would enable the creation of novel ultra-small devices. However, finding a two-dimensional material with similar properties as silicon has proven very difficult.

Recently, a new class of two-dimensional materials, the so-called metal-chalcogenides with the chemical formula MX (where M denotes either indium or gallium and X denotes either selenium or telluride), have generated much excitement. These materials absorb light at similar frequencies as silicon and feature highly mobile electrons. It is possible to modify the properties of these materials by stacking different layers on top of each other and such multilayers have already been harnessed in highly sensitive, ultrathin photodetectors.

In this PhD project, you will study the electronic and optical properties of metal-chalcogenide multilayers using advanced electronic structure methods ranging from density-functional theory to many-body perturbation theory within the GW approach. In addition, you will collaborate with other researchers at the London Centre for Nanotechnology, the Thomas-Young Centre for Theory and Simulation of Materials and the National Graphene Institute.

Applicants should have a Master’s degree in Physics, Chemistry or Materials Science and a strong interest in both experiments and computer simulations. This project is well suited to a self-motivated student. You should also have excellent communication skills including proven ability to write in English.

We encourage informal enquiries about the project, which can be made to Dr. Johannes Lischner at Further information on the group's research interests can be found at

This PhD studentship is funded by The Royal Society and is open to UK home students or European students who have spent the last three years in the UK. The studentship will cover tuition fees plus the standard maintenance stipend of £16,553 per annum.
