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.
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.
The group has secured funding for a 3-year license of NextNano for quantum device simulation. This is part of the University of Manchester’s COVID research-recovery fund, and will be led by group member Nikesh.
Patrick was the internal examiner for Vasilis Georgiadis, a member of Dr Darren Graham‘s research group in Manchester. Vasilis defended his thesis entitled “Terahertz-driven manipulation of electron bunches using dielectric-lined waveguides“.
Congratulations and an “au revoir” to group PhD student Stefan Skalsky, who has accepted a postdoctoral position at the Lancaster University in the group of Qiandong Zhuang. He will work on mid-infared optoelectronics for sensing applications.
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.

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.
