Nanowire Week 2022: Talks and Posters
Nanowire week 2022

Group members Dr Stephen Church and Nikesh Patel have presented their work at the 2022 Nanowire Week meeting in Chamonix, France.

Stephen gave an oral presentation on his recent research on “Nanowire facet reflectivity and lasing performance using high-throughput interferometry“.


Nikesh presented a poster on his work on “High Intra- and Interwire Uniformity in 2D Radial GaAsP/GaAs Core/Shell Triple Quantum Well Structures


Congratulations to first group PhD student Juan (Arturo), who managed to graduate today. Having passed his viva in March 2020, it was a long wait to return to Manchester. He is now working with Synaptec in Glasgow.

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*STAR, to apply Bayesian driven yield optimization to optoelectronic nanowires.

More details about the project are available at the FindAPhD site. The closing date is April 1st.

New Review : Measuring, controlling and exploiting heterogeneity in optoelectronic nanowires

Interwire and intrawire inhomogeneity

Group PhD students Ruqaiya Al-Abri and Hoyeon Choi have written an invited review article for JPhys Photonics, published today.

Lead author Ruqaiya Al-Abri describes this work:

Among the one-dimensional structures, semiconductor nanowires have attracted great attention; from the growth process to the production of functional devices they have been widely studied. The growth condition of the nanowires can lead to non-uniformity (disorder) in the crystal structure, morphology, and geometry of the nanowire. Consequently, this affects the functionality of individual and/or ensembles of nanowires. However, researchers have benefited from disorder; it has been shown that disorder can enhance the performance of ensemble of nanowires such as in photovoltaic devices. This review article attempts to understand the disorder in these structures, investigates the origin of the inhomogeneity within “interwire” and between “intrawire” nanowires, and outlines different approaches to correlate disorder to functional parameters and hence optimize the performance of the nanowires.

EPSRC-funded PhD position now available

A fully funded EPSRC studentship (DTP) will be available in the group for a September 2021 start. This studentship is associated with the “Big-data for nano-electronics” project, and is open to UK-based applicants (EU applicants living in the UK may also be eligible for some support).

The project will develop a framework for producing and analysing high-throughput imaging and spectroscopy data for inhomogeneous nano-electronic devices, and will include both experimental and computational work.

In particular, students with a good first degree or MSc in physics, electronic materials, nanotechnology or photonics are encouraged to apply.

For further details, please contact Patrick. Applications must be made via the University site.

Congratulations to group PhD Stefan Skalsky

A post-viva call

A huge congratulations to group PhD student Stefan Skalsky (co-supervised with Prof. Wendy Flavell) who passed his PhD viva with minor corrections. Even more impresively, he managed to deal with the challenges of a video-cal based viva.

His examiners were Prof. David Mowbray (Sheffield) and Prof. Mark Dickinson (Manchester).
