New Paper: Defect-Free Axially Stacked GaAs/GaAsP Nanowire Quantum Dots with Strong Carrier Confinement

In a new collaboration between Yunyan Zhang and Profs. Huiyun Liu (UCL), Ana Sanchez (Warwick) and David Mowbray (Sheffield) we report the fabrication and measurement of a GaAs/GaAsP quantum dot-in-wire structure in Nano Letters. While many material architechtures have been explored for single photon emission, the GaAsP-GaAs system provides

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 Paper - Optical Study of p-Doping in GaAs Nanowires for Low-Threshold and High-Yield Lasing

Our new work on large-scale statistical spectroscopy to optimize nanowire lasers is published today in Nano Letters. In this work, PhD student Arturo studied thousands of nanowires to identify the lowest threshold nanowire, as well as to model emission to identify the primary sources of non-radiative emission. By quickly sorting
