Training in: High resolution scanning transmission electron microscopy, atomic resolution X-ray and electron energy-loss spectroscopy, scanning electron microscopy, simulation and image/data analysis.

Antimonide semiconductors have many useful properties that set them apart from other III-V materials, including small band gaps (e.g. leading to low energy devices that save electricity) and very high carrier mobilities (e.g. giving very fast devices).  However, they are difficult to manufacture in comparison with silicon and material quality is still an important issue.  Electron microscopy allows the study of structure and defects at the atomic scale and gives essential information that informs crystal growth and device manufacture.

The research will focus on atomic scale investigations of III-Sb nanostructures and devices using state-of-the-art aberration-corrected electron microscopy. We seek to measure the composition of interfaces at the atomic scale and understand the origin of defects such as dislocations that form in the material. The aim of the project is to measure electronic structure, short- and long-range order, composition, optical and transport response of different materials and devices, linking these measurements to device processing and materials production.

The candidate will learn and use multiple electron microscopy based techniques including aberration-corrected scanning transmission electron microscopy(ac-STEM), electron channeling contrast imaging (ECCI), electron-beam induced current (EBIC) and electron-beam excited optical luminescence (Cathodoluminescence, CL).


Institution: The University of Warwick is a research-intensive institution, ranked in the top 10 in the UK and 62nd in the world. The University invests heavily in research infrastructure and the electron microscopy facilities are world-class.
Institute/Laboratory: The Department of Physics has over a thousand staff and students. Our research spans fields of condensed matter, astrophysics, elementary particles, plasmas, soft matter and theoretical physics, with staff publishing over 500 research papers each year. We take on 30-40 new PhD students each year who work across the whole range of research interests as well as in interdisciplinary Centres for Doctoral Training.
Location/City: The University has one of the largest campuses in the UK, and straddles the Warwickshire/ West Midlands boundary on the edge of Coventry.


We seek an excellent, open-minded and team-spirited PhD candidate with:
Graduation: a Physics, Chemistry or Engineering degree.
Post-graduation: successful candidates will have a separate Master in a scientific field, or, an integrated Master (MPhys, MSci, MEng, MChem etc.). Previous experience in a research environment involving solid state physics, materials science or similar will be positively considered.
Other: The successful candidate should have good knowledge and interest in both experimental and theoretical work.
