New Publication: Self-Catalyzed AlGaAs Nanowires and AlGaAs/GaAs Axial Heterostructures Grown by Molecular Beam Epitaxy
A new paper in collaboration with the Huiyun Liu group (UCL), Ana Sanchez group (Warwick) and David Mowbray group (Sheffield).
In our contribution, led by Stephen Church, we showed that a previously low quality structure (AlGaAs) can be made to emit strongly at room temperature.

New Publication: Wavelength-tunable femtosecond pulsed laser for the characterisation of solid-state sensors
Group PhD Nawal Al-Amairi (now lecturer at UTAS Oman) has published a device work in collaboration with the particle physics team at Manchester.
In this new work, an ultrafast laser system is used to characterize different device structures for particle detection, revealing a broad spectrum approach to novel 3D detectors.
Fairwell: Stephen Church
A farewell to group postdoc (and later research Fellow) Stephen Church, who (after 14 years) leaves the university for a new role as a lecturer at the University of Salford. Many thanks for all your work, and we look forward to seeing what you achieve next!
New Publication: As-Flux-Induced Diameter Control in GaAs Nanowires
A new paper has been published in J Phys Chem C led by the Huiyun Liu group at UCL, with Stephen Church as lead Manchester contributor.
In this work, an improved growth approach for GaAs nanowires is introduced that provides a route to generate diameter control and a method to

New Publication: Interfaces in Epitaxially Grown Zn3P2 Nanowires and Their Composition-Dependent Optoelectronic Properties for Photovoltaic Applications
A new paper in collaboration with Simon Escobar Steinvall (Lund University) was accepted for publication in Chemistry of Materials.
In this work, high throughput spectroscopy was used to understand the variation in emission energy of ZnP nanowires in InP. This materials, whilst relatively old, is now seen as a potential
Oxford Nanotechnology talk and Celebration
Patrick gave a group highlights talk at the Oxford Nanotechnology Symposium at the Clarendon Building. This symposium was arranged in honour of Prof. Chennupati Jagadish being elected as a Fellow of the Royal Society.
Graduation day: Nikesh Patel
Congratulations again to Dr Nikesh Patel who graduated in the sunshine of Manchester.
He'll be taking a role with the startup aegiq in Sheffield.
New Paper: Microstructure determines crystallinity-driven singlet fission efficiency in diF-TES-ADT
Dr Hoyeon Choi has had the final paper of his PhD accepted in Scientific Reports. This work, in collaboration with Prof Jenny Clark at the University of Sheffield uses hyperspectral mapping to study spatial inhomogeneities in singlet fission materials. Combined with time-resolved spectroscopic measurements, this work shows the role of
