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