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
Photonics West 2020 - presentation and proceedings
The talk and proceedings for Patrick’s recent invited talk at Photonics West is now available online.
“A needle in a needlestack” describes how our recent work on Manchester on inhomogeneity can provide more information about functional performance than a homogeneous population can.

New arXiv paper: Defect-Free Axial GaAs/GaAsP Nanowire Quantum Dots with Strong Carrier Confinement
We have uploaded a new paper on quantum-dot-in-nanowire structures to the arXiv. Working with colleagues at University College London, the University of Warwick, the University of Sheffield and the University of Copenhagen, this work demonstrates the growth of high-quality GaAs quantum dot inclusions in a GaAsP nanowire, with evidence for
Invited Talk at Photonics West 2020
Patrick gave an invited talk at Photonics West 2020 in San Francisco, in the session Novel Nano Structure. This talk convered recent work on ultra-low threshold nanowire lasers and experimental end-cavity reflectivity measurements in nanoscale systems.
New Paper: Characterisation, Selection and Micro-Assembly of Nanowire Laser Systems
Our collaborative work on the selection, transfer and testing of semiconductor nanowire lasers has now been published in Nano Letters.
In this work, growth colleagues at ANU prepared nanowire lasers which were characterised at Manchester. This characterisation was used to select bins of nanowires, which were transferred using a cutting
