We demonstrate the design, fabrication, and measurement of a switchable distributed Bragg
reflector (DBR) that can be thermally switched from a close-to-zero reflective OFF state to a …

Chiral nanostructures offer the ability to respond to the vector nature of a light beam at the
nanoscale. While naturally chiral materials offer a path towards scalability, engineered …

Ge 2 Sb 2 Te 5 (GST), a phase change material, generally exhibits two-step crystallization
(amorphous→ fcc→ hcp) to store and process data. The present study reports the …
