New Publication: Improving Quantum Well Tube Homogeneity Using Strained Nanowire Heterostructures

Group PhD student Nikesh Patel has just had his first paper accepted in ACS Applied Materials and Interfaces. His study uses a new methodology to understand how quantum "shells" - less than 10nm thick - vary both within single nanowires, and between them. By using automated high-throughput approaches on over

New Publication: Holistic Nanowire Laser Characterization as a Route to Optimal Design

Group postdoc Stephen Church has just had a paper accepted into Advanced Optical Materials. In this work, he reports the study of thousands of individual nanowire lasers, using advanced statistical methods to identify a route to optimization. Photonic integrated circuitry is rapidly emerging as an alternative to electronics for specialist

Conference Presentation: UK Semiconductors

Group postdoc Stephen Church presented a talk entitled “Disentangling Gain, Distributed Losses and End-Facet Losses in Freestanding Nanowire Lasers using Automated High-Throughput Micro-Spectroscopy” at UK Semiconductors in Sheffield, UK. This collaborative work between Manchester and colleagues in Zhejiang and University College London reported a multimodal correlative approach to studying nanolasers.

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
