Semiconductor Spectroscopy and Devices

• May 2022: Congratulations and good luck to Dr Naresh Kumar who has left the group after 13 years to take up a lectureship at Cardiff University.
• May 2022: Congratulations to (soon-to-be Dr) Douglas Cameron on the successful defence of his PhD thesis, “Nanocharacterisation of III-Nitride Semiconductors”.
• May 2022: Fabien Massabuau has been nominated for a Strath Union Teaching Excellence Award. Here are some pictures of the award ceremony in the new Union’s new building.
• September 2021: Lucia Spasevski has successfully defended her thesis “Correlation of composition and luminescence in AlGaN epilayers”, in which she compared the results of X-ray microanalysis and cathodoluminescence measurements. Congratulations, Lucia!
• May 2021: Congratulations to Dr Alessandro Rossi on his promotion to Senior Lecturer!
• May 2021: Well done to Aeshah Alasmari on the successful defence of her PhD thesis, “Characterisation of III-nitrides in the scanning electron microscope”!
• May 2021: We are joined by colleagues from Cambridge as Dr Jonas Lähnemann from PDI in Berlin gives a seminar on Revisiting the determination of the carrier diffusion length in GaN from cathodoluminescence spectroscopy. The next seminar will be on 9th June, when Dr Masaya Kataoka from NPL will talk on Electron quantum optics for electrical metrology
• March 2021: Dr Budhika Mendis from Durham University gives a group seminar on Towards accurate simulation of EBSD and ECCI signals
• October 2020: Congratulations to Dr Alessandro Rossi on the award of a prestigious UKRI Future Leaders Fellowship! Alessandro’s project is entitled “Quantum Electronics in Silicon Carbide (QELTIC)” and aims to develop the first generation of electronic devices to address quantum states in silicon carbide (SiC). Read the announcement here.
• October 2020: Sretno, Lucia! We held a virtual goodbye party for Lucia, who is off to work for work for Quorum Technologies in Lewes. Ruth won the cake competition with her lemon cheesecake cupcakes. (Sorry, no saltire in my Eurovision bunting.)
• August 2020: Fabien, Rob and Paul are co-editing a special issue of Micromachines on Wide Bandgap Semiconductor Based Solar-Blind Photodetectors, together with Prof. Weihua Tang and Prof. Chong-Xin Shan.
