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.

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

Kick-off meeting: Kubos Semi IAA

Patrick and Stephen traveled to Cardiff University to meet Kubos representatives as part of the Impact Accelerator Kick-off meeting. Stephen will spend half of his time developing our spectroscopy tools to support novel materials develop over the next 12 month as part of a secondment to Kubos.

New Grant - EPSRC Impact Accelerator with Kubos Semi

The group has been awarded a 1-year “impact accelerator” grant with Kubos Semi, to fund a 6 month secondment of group PDRA Stephen Church. In this project, Stephen will translate our high-throughput methodology towards in-line optimization of emerging semiconductor materials. Kubos develop cubic-phase GaN which can be grown on large

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
