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).
