Congratulations to Hoyeon Choi!

A huge congratulations to group PhD Hoyeon Choi for successfully defending his thesis today. Hoyeon's examiners were Sam Bayliss (Glasgow) and David Binks (Manchester). Hoyeon was the fourth postgraduate student through the OMS group, and the first to be impacted by COVID. Nevertheless, he built up a substantial series of

Conference Presentation: CMD 2022

Two of the group gave oral presentations at CMD29 in Manchester. Group PhD student Hoyeon Choi reported his work on the “Impact of Microstructure of Crystallinity driven singlet fission efficiency in diF-TES-ADT“, a collaboration between Jenny Clark (Sheffield) our our group. Group PDRA Stephen Church reported his work on “Disentangling

New Paper: Holistic Determination of Optoelectronic Properties using High-Throughput Spectroscopy of Surface-Guided CsPbBr3 Nanowires

Optoelectronic materials form the building blocks of crucial components of modern technology, including solar cells, CCDs, lasers and LEDs. The past decade has seen significant developments in materials science that enable the shrinking of these materials to the nano-scale. These advancements have also created entirely new technologies based around light

New Review : Measuring, controlling and exploiting heterogeneity in optoelectronic nanowires

Group PhD students Ruqaiya Al-Abri and Hoyeon Choi have written an invited review article for JPhys Photonics, published today. Lead author Ruqaiya Al-Abri describes this work: Among the one-dimensional structures, semiconductor nanowires have attracted great attention; from the growth process to the production of functional devices they have been widely

New Paper: Visualizing the role of photoinduced ion migration on photoluminescence in halide perovskite grains

Group student Hoyeon has had a paper accepted in the RSC Journal of Materials Chemistry C, studying the photo-brightening effect in perovskite grains using correlated optical and chemical mapping. In collaboration with the Flavell group and the NanoSIMS group at Manchester, this study linked luminescence lifetime and emission energies to

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

Welcome to Hoyeon Choi!

A welcome to Hoyeon Choi, who joins the group as a PhD student from the Advanced Photonics Research Institute at the Gwangju Institute of Science and Technology. Hoyeon is co-supervised by Wendy Flavell, and will focus on the role of morphology on energy dynamics in novel photovoltaic materials.
