Silicon Microspheres for Super-Planckian Light Sources in the Mid Infrared

April 28, 2023

Silicon microspheres with diameters in the 2–3 micrometre range act as photonic nanocavities. At high temperature, their Mie resonances produce highly selective mid-infrared emission, including modes above the…

Thermal Emission of Silicon at Near-Infrared Frequencies Mediated by Mie Resonances

December 3, 2019

Silicon microspheres heated to around 800 °C produce pronounced near-infrared thermal emission peaks associated with high-quality Mie resonances, reaching an experimental Q factor of 400.

Groove-assisted solution growth of lead bromide perovskite aligned nanowires

April 1, 2019

A low-cost templating method based on replicated CD and DVD grooves produces uniform all-inorganic and hybrid lead bromide perovskite nanowires with strong photoluminescence and light-guiding behaviour.
