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.

Complete crossing of Fano resonances in an optical microcavity via nonlinear tuning

November 6, 2017

Nonlinear thermo-optical tuning continuously reshapes and crosses Fano resonances in chip-integrated microresonators, enabling direct observation of interactions between quasi-degenerate optical modes.

Colloidal Crystal Thin Films Grown into Corrugated Surface Templates

March 16, 2010

Patterned DVD surfaces act as templates for one- and two-dimensional colloidal crystals, producing a rich variety of particle arrangements controlled by the relationship between groove width and sphere…

Layering transitions in confined colloidal crystals: The hcp-like phase

April 10, 2007

Confined nearly hard spheres exhibit smooth morphological transitions through a general hcp-like ordering that adapts continuously to changes in cell thickness from two to six layers.
