This post arises from a newly awarded EPSRC Programme Grant “Quantum and Many Body Physics Enabled by Advanced Semiconductor Nanotechnology” in Sheffield. This programme will employ 8 postdoctoral researchers in Sheffield, and will provide highly creative and productive environment based around our state-of-the-art optical spectroscopy labs and sample fabrication facilities.

This post is advertised together with another position focused on fabrication of 2D semiconductors and their structures.

The goal in this post is to work on two-dimensional (2D) materials, both in their few-atom thick and up to few 100 nm thin film forms, and in particular investigate various heterostructures fabricated by layer stacking relying on van der Waals forces. The idea is to create new type of excitonic/electronic and photonic ‘designer’ materials by using ‘twist’ or relative in-plane rotation between the adjacent atomic layers. In this revolutionary approach, a wide variety of properties in such van der Waals materials can be controlled by the relative rotation. Such controllable properties will further be used and studied in photonic micro- and nano-cavities, where the regime of strong light-matter interaction will be one of the central topics.

In this post you will design and optically characterise such twisted few-atomic-layer structures and devices, and if necessary will contribute to device fabrication along with dedicated staff and PhD students. Optical characterisation will include photoluminescence, absorption, Raman, various microscopy techniques, and near-field optical spectroscopy with 20 nm resolution in the new centre in Sheffield (available from January 2022). Structures to be studied will include few-atomic-layer semiconductors and various photonic structures made from 10-200 nm thick films of layered materials.

You will have a strong background in solid state physics, and have completed or be in the final stages of your PhD in this or relevant discipline. Expertise in optical spectroscopy of 2D materials or other semiconductor nano-structures, semiconductor device fabrication, various microscopy techniques as well as photonics is highly desirable.
