报告摘要

Vanadium dioxide undergoes a unique temperature-driven, reversible phase transition from the insulating to the metallic phase when heated above its transition temperature of 67 degrees Celsius. These two phases differ drastically in their electrical, mechanical, and optical properties. Based on this phase-transition material, we have developed various micro-mechanical and nano-photonic devices, including MEMS/MOEMS, metamaterial/metasurface, and smart thermal emitters. In this talk, I will give an overview of our work on the above topics.
