Research: XRF and XEOL at ESRF

Patrick, Stephen and Nikesh visited the ID16 beamline at ESRF Grenoble to carry out nano X-ray imaging. This was led by Dr Valentina Bonino, beamline scientist; four 24 hour shifts were used to measure combine XRF (X-Ray Fluorescence) and XEOL (X-Ray excited optical luminescence) with 60nm resolution on doped and

Conference Talk: Stephen Church at UKNC Glasgow

Group postdoc Stephen Church presented a talk at UKNC (the UK Nitrides Conference) in Glasgow, Scotland. His talk focussed on nitride-related aspects of our research, "Holistic characterization of GaN and III/V nanowires using experimental big data".

Conference Talk: Stephen Church at EUROMAT 2023

Group postdoc Stephen Church presented a talk at EUROMAT23, in Munich, Germany. His talk, on "Understanding Nanowire Laser Performance - Insights from Experimental Big-Data" drew together material from collaborators spanning Australia, London, Jena, and Cambridge. By applying a modular experiment with high-throughput capability he showed that some findings - such

Pint of Science 2023: Shining a Light on Quantum Materials

Group PDRA Stephen Church gave a public talk on our research at the annual Pint of Science Festival. He spoke to a paying audience at The English Lounge about automation, disorder, and the benefits of nano-scale lasers for the world.

New Publication: Sub-Picosecond Carrier Dynamics Explored using Automated High-Throughput Studies of Doping Inhomogeneity within a Bayesian Framework

Nano-materials are hard to precisely manufacture. By measuring >10k, we use their disorder to understand their performance in a paper in Small.

Outreach talk - Stephen goes to Salford

Group postdoc Stephen Church has given an outreach talk at the University of Salford. This talk was delivered to undergraduate students, and covered the scientific and industrial spectroscopy work in our group.

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

Presentation Prize: Stephen Church at Rank Prize Symposium

Group postdoc Stephen Church was awarded the “best early-career-researcher” presentation prize at the Rank Prize Symposium meeting in Grasmere. The meeting Nanowire Photonics was chaired by Prof. Martin Dawson (Strathclyde), Prof. Hannah Joyce (Cambridge) and Prof. Michael Johnston (Oxford). Congratulations to Stephen!

Conference Presentation: Rank Prize Symposium in Nanowire Photonics

The group was well represented at the Rank Prize symposium in Grasmere. The high-throughput and automation session included invited talks from Patrick, Stephen Church and Ruqaiya Al-Abri.
