About

There has been a recent rapid development in the development of perovskite materials as radiation detectors. Perovskites have many ideal properties for radiation detection applications, including the presence of high-Z atoms such as Cs and Pb for good X-ray and gamma ray efficiency, good charge transport and/or scintillation properties, and the ability to fabricate the materials using relatively straightforward solution processing methods. Perovskites have been successfully demonstrated both as X-ray imaging detectors and also as detectors for gamma ray spectroscopy. As gamma detectors, perovskites have the potential to offer a low-cost room temperature semiconductor technology to replace CZT and Silicon. 

In this research project you will investigate a range of next-generation “double perovskite” materials and assess their suitability for use as gamma ray detectors. We are looking for a PhD student with a first degree either in Physics or Chemistry, and with an interest in working in this exciting multi-disciplinary experimental project. You will learn a range of different synthesis methods to create perovskite materials, and you will then produce prototype radiation sensors which will be tested for their suitability as gamma detectors. using radiation techniques.

You will join a large and well-equipped research team led by Professor Sellin, which is a world-leading group working on perovskite radiation detectors. The team currently comprises three academic staff,  one postdoctoral researcher and five PhD students, and is split between the Physics and Chemistry departments. The Surrey team is also a member of the US “Interaction of Ionizing Radiation with Matter (IIRM)” University Research Alliance led by Penn State University, and you will have opportunities to collaborate and work with members of this US consortium.

Applicants with first degrees in either Physics or Chemistry are welcome to apply for this studentship. Supervision will be provided from both the Physics and Chemistry departments, and you will work in a number of different laboratories across both departments. We don’t expect you to already have an expert knowledge of all the topics within this PhD, but just to have an enthusiasm to learn more about this exciting inter-disciplinary research!

Eligibility criteria

Applicants must hold a first degree in Physics or Chemistry, or a Masters degree in Physics, Chemistry or related subjects. Subject to the University’s standard entry requirements.

This studentship is open to UK students only.

Non-native English speakers will be required to have IELTS 6.5 or above (or equivalent) with no sub-test of less than 6.

How to apply

Applications should be submitted via the Physics PhD programme page on the "Apply" tab.

Please clearly state the studentship title and supervisor on your application.
