Congratulations to group PhD student Ruqaiya Al-Abri for completing her PhD viva on "Correlative Optoelectronic Measurements for Optimization of Semiconductor Nanolasers". The examiners were Jack Alexander-Weber (University of Cambridge Physics) and David Binks.
Congratulations to group PhD student Nawal Al-Amairi on passing her PhD viva with a thesis entitled "Optimisation of Photo- and Particle Detectors using Ultrafast Scanning Photocurrent Microscopy" with minor corrections! Thanks to both examiners: Qiandong Zhuang (Lancaster) and Iain Crowe (Manchester).
Patrick chaired a two-day workshop on Scale-up and Standardization for Photonic Quantum Technology at NPL Teddington. This event brought together over twenty speakers from academia, industry, national labs, metrology and funders to discuss opportunities and challenges in scaling-up photonic quantum technology. With over 80 registered attendees, this M4QN/NPL/University
Patrick gave an invited talk at Nanowire Week 2023, at Georgia Tech in Atlanta Georgia. This event brought together over 100 academics and researchers from around the world to discuss the major findings and future direction for the nanowire field, spanning sensing, photovoltaics, microscopy, lasing and more.
A warm welcome to the group to new PhD student Ishika Das! Ishika joins from a MSc degree at Bristol. She will work on a project to simulation, measure and optimize novel non-linear optoelectronic materials, working with her co-supervisor Dr Iain Crowe and international partners including Prof. Hong Liu (A*
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
Green LEDs remain low efficiency compared with their blue counterparts, but are required for future display technology. Power-dependent measurements show that current- rather than defect-management is crucial to improving efficiency.
Lanthanide elements have distinctive and long-lived light emission. Holding multiple lanthanides close together provides a route to creating new biological imaging molecules.
Computation with light instead of electricity will increase speed and energy efficiency. We show a route to growing lasers directly onto chips with high repeatability to enable this technology.
Valentina Bonino, beamline scientist at the ESRF in Grenoble, visited the group to discuss collaboration on nanomaterial characterization.
