Back to work - PSI labs reopen
The Photon Science Institute laser labs are now reopened after nearly 19 weeks of closure due to the novel coronavirus shutdown. All lasers are back on, and reseach will resume over the upcoming week or two.

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.
Postdoctoral Research Position Available: Big-Data for Nano-Electronics
A 2-year postdoctoral position is available in the group to work on data acquisition and analytics pipeline on the big-data for nano-electronics project. The post has the potential to be extended to 4 years.
The successful candidate will apply statistical approaches to large-scale data produced by high-throughput spectroscopy and imaging
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,
Seminar : LIV.DAT
Patrick gave a virtual seminar at Liverpool Big Data Science Centre for Doctoral Training (LIV.DAT) on “Big-data for nano-electronics“. Thanks to Prof. Carsten Welsch for the invitation!
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 Project: Big-Data for nano-electronics
Patrick has been awarded a 4-year research fellowship from UKRI for a project on “big-data for nano-electronics”. This Future Leaders Fellowship will enable Patrick to focus on building a research group to develop a new methodology for accelerating the study of functional nanotechnology.

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
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
PhD Viva: Arturo
Arturo Alanis (the first PhD student of the group) had a successful PhD viva today. His thesis examiners were Dr Hannah Joyce (Cambridge) and Dr Jessica Boland (Manchester).
Arturo has already secured a postdoctoral position to start in a few weeks; we’ll be sad to see him go, but
