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

New preprint: Holistic nanowire laser characterization as a route to optimal design

Group postdoc Stephen Church has submitted his most recent work to the arXiv preprint server. In this new work, Stephen carried out optical, microscopic, and electron micrograph characterization of over 5000 nanowire lasers. By correlating geometry effects which affect the nanolaser cavity, and material quality that affect gain material, we

Conference Presentation: CMD 2022

Two of the group gave oral presentations at CMD29 in Manchester. Group PhD student Hoyeon Choi reported his work on the “Impact of Microstructure of Crystallinity driven singlet fission efficiency in diF-TES-ADT“, a collaboration between Jenny Clark (Sheffield) our our group. Group PDRA Stephen Church reported his work on “Disentangling

New Paper: Optical Characterisation of Nanowire Lasers

Group postdoc Stephen Church and PhD student Ruqaiya Al-Abri collaborated with Dhruv Saxena at Imperial College London to produce a review of methods to characterise nanowire lasers. This article, forming part of a celebration issue for the birthday of colleague Prof. Chennupati Jagadish (at the Australian National University) seeks to

Panel discussion

Patrick took part in a virtual panel discussion featuring collaborator Prof. Fu Lan (Australian National University) on the topic of nanowire quantum well arrays. The ICANX talk was moderated by Haixia Zhang of Peking University, and featured Weida Hu (SITP) and Noushin Nasir (Macquarie). The session is available to view

Funded PhD position with A*STAR

The group is now advertising for a funded PhD position as part of the A*STAR ARAP scheme, in collaboration with Kedar Hippalgaonkar of A*STAR and NTU in Singapore. The project will build on the high-throughput techniques developed in the Manchester group, and the Bayesian optimization approaches at A*

Physics and applications of semiconductor nanowire lasers - book chapter published

Patrick has contributed a chapter to the new textbook “Semiconductor Nanodevices“, edited by Prof. David Ritchie (University of Cambridge) and published by Elsevier. In his chapter on Physics and Applications of Semiconductor Nanowire Lasers, common features, design rules, seminal works and an outlook for future development are provided.

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 Publication: Self-Catalyzed AlGaAs Nanowires and AlGaAs/GaAs Nanowire-Quantum Dots on Si Substrates

A new collaborative paper led by Giorgos Boros and the team of Xuezhe Yu and Huiyun Liu at University College London has been published in J Phys Chem C. In this work, Giorgos reported the development of high quality ternary nanowires (AlGaAs) grown via MBE. While the AlGaAs/GaAs heterostructure
