Dr Fabien Massabuau

Senior Lecturer



Personal statement

Fabien Massabuau joined the Department Physics as a Chancellor’s Fellow in September 2019. His research focussed on wide bandgap semiconductors for ultraviolet optoelectronic devices, with a main emphasis on α-Ga2O3 and h-BN.

Prior to that, Fabien was at the Department of Materials Science and Metallurgy at the University of Cambridge for his PhD (2011-2015) and post-doc (2015-2019). In Cambridge, Fabien focussed on understanding the correlation between the nanostructure of III-Nitride materials and their optical properties. He actively participated in the development of a “multi-microscopy” methodology to observe the exact same nanoscale feature under several different microscopes (AFM, SEM-CL, TEM). This work led to new understandings on the properties of defects (dislocations, trench defects) in these materials.

Fabien has authored 40 peer-reviewed articles cumulating >600 citations, 2 book chapters, 1 mobile application and is involved withDoctoral Researcher Awards (committee member), SN Applied Sciences (editorial board).

The project aThe instrument is a Benchtop X-Ray Diffractometer, which is a device that can analyse the structure and composition of various materials. It can provide data on crystal and molecular structure, phase identification and quantification, and crystallite size and strain. It is suitable for a wide range of inorganic and organic materials in different forms, such as powders, films, or solids. The instrument is compact, fast, easy to use, and low-cost, making it ideal for routine and high-throughput analysis. It can support research in many fields, such as materials science, engineering, chemistry, energy, and healthcare.
The instrument was acquired through an EPSRC Core Equipment fund, with an internally allocated £64k from the University of Strathclyde
