New Paper : Facet-Related Non-uniform Photoluminescence in Passivated GaAs Nanowires

Our collaborative work on spatially inhomogeneous recombination in semiconductor nanowires has been published in a special issue of Frontiers in Chemistry. The work, led by Dr. Nian (Jenny) Jiang at the University of Cambridge reports the spatially varying emission intensity from passivated nanowires. By comparing the bulk emission to buried

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 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. Project Summary The modern world runs on

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

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

New arXiv paper - Characterisation, Selection and Micro-Assembly of Nanowire Laser Systems

Our new paper produce in collaboration with Michael Strain and Antonio Hurtado (University of Strathclyde) and the Jagadish group (Australian National University) is now available on the arXiv. In this work, we combine high-quality nanolaser growth (ANU) with high-throughput optical spectroscopy (Manchester) and high-speed pick-and-place technology (Strathclyde) to demonstrate scaled-up

University of Oxford Condensed Matter Physics Seminar

Patrick gave the Oxford Condensed Matter Physics seminar on A needle in a needlestack – exploiting functional inhomogeneity for optimized nano-optoelectronics. In this talk, he presented on recent advances in using high-throughput spectroscopy to study nanowires for optoelectronic applications.

Collaborator visit to Sheffield

Ruqaiya and Patrick visited Prof. David Mowbray at the University of Sheffield to discuss nanowire spectroscopy research.
