New Paper: Microstructure determines crystallinity-driven singlet fission efficiency in diF-TES-ADT

Dr Hoyeon Choi has had the final paper of his PhD accepted in Scientific Reports. This work, in collaboration with Prof Jenny Clark at the University of Sheffield uses hyperspectral mapping to study spatial inhomogeneities in singlet fission materials. Combined with time-resolved spectroscopic measurements, this work shows the role of

Welcome to Stefan!

The group welcomes Dr. Stefan Skalsky to the group as a short-term postdoctoral researcher. He will lead a pump-prime project on integrating single photon spectroscopy to near-field microscopy as part of a UMRI-funded project with Jessica Boland.

Au Revoir to Stefan Skalsky

Congratulations and an “au revoir” to group PhD student Stefan Skalsky, who has accepted a postdoctoral position at the Lancaster University in the group of Qiandong Zhuang. He will work on mid-infared optoelectronics for sensing applications.

Congratulations to group PhD Stefan Skalsky

A huge congratulations to group PhD student Stefan Skalsky (co-supervised with Prof. Wendy Flavell) who passed his PhD viva with minor corrections. Even more impresively, he managed to deal with the challenges of a video-cal based viva. His examiners were Prof. David Mowbray (Sheffield) and Prof. Mark Dickinson (Manchester).

Stefan Skalsky thesis submission

Congratulations to lab member Stefan Skalsky, who submitted his PhD thesis today. He work, entitled “Interferometric Time-correlated Single Photon Counting for Nano-optoelectronic Characterisation” covers his research on the i-TCSPC tool.

New Paper: Carrier dynamics and recombination mechanisms in InP twinning superlattice nanowires

A new paper has been published in Optics Express, led by collaborator Xiaoming Yuan at Central South University (Changsha) and growth colleagues in the group of Prof. Jagadish at Australian National University. In this work, novel “twinning-superlattice” nanowires are grown. Once passivated, this growth method produces extremely high quality nanowires,

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

New Paper: Heterostructure and Q-factor engineering for low-threshold and persistent nanowire lasing

Group PhD student Stefan Skalsky’s paper on semiconductor nanowire lasing has just been published in Light: Science and Applications. In this new work, Stefan used his newly developed Interferometric Time-Correlated Single Photon Counting system (i-TCSPC) to measure the coherence length of laser emission from nanowires grown by the Liu

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.

Photon 2018

Both Stefan and Arturo will present at Photon 2018 in Aston, UK (September 3rd-6th, 2018). Stefan presented a poster on “Time and Spectrally-Resolved Microscopy of GaAsP-GaAs core-shell Quantum Well Lasers“, describing some recent work with collaborators in the group of Prof. Huiyun Liu at University College London. Arturo presented a
