Conference Talks: EUROMAT 2021

Group PhD student Ruqaiya Al-Abri and postdoctoral researcher Stephen Church both gave oral talks at EUROMAT 2021. The conference, originally scheduled to be held in-person in Vienna, ran as a virtual meeting.

Ruqaiya gave her first oral presentation on her collaboration with Lund University on “High-throughput spectroscopy for optimizing internal quantum efficiency in Aerotaxy-grown Zn-Doped GaAs Nanowires” in the Nanowires and Nanotubes session.

Stephen presented his new work, (and first in the group) on a recent collaboration with the Weizmann Institute on “Carrier dynamics and recombination mechanisms from high-throughput study of strained CsPbBr3 perovskite nanowires“.

New Conference Proceeding: Effect of Micron-scale Photoluminescence Variation on Droop Measurements in InGaN/GaN Quantum Wells

Rachel Barrett (a PhD student in the Binks group in Manchester) has had a conference proceeding published in collaboration with the OMS group. The study, on micro-scale spectroscopy of GaN-based quantum wells was presented at Photon 2020 and was carried out in collaboration with the Department of Materials Science at Cambridge.

Conference Proceedings: Spatially and temporally resolved degradation in antisolvent treated perovskite films

Group PhD student Hoyeon Choi has had a conference proceedings accepted for SPIE Europe 2020. As this conference has been cancelled, his talk is available throught the SPIE Digital Form.

In his work, Hoyeon describes the application of confocal and time-resolved spectral mapping to study and understand photobrightening and degradation processes in a prototypical perovskite material fabricated with and without use of anti-solvent treatment.

The presentation and paper are available online now.

Talk at UK Semiconductors 2019

Group PhD student Stefan Skalsky gave a talk at the UK Semiconductors meeting in Sheffield. His talk, on “Nanosecond lasing and mm-scale optical coherence length in GaAsP/GaAs Quantum-Well Nanowire Lasers” descibed his recent work using interferometric time-resolved spectroscopy to reveal the end-facet reflectivity in nanowire lasers.
