Abstract:

Thermal radiation represents a ubiquitous aspect of nature. Any object at finite temperatures emits thermal radiation due to thermally induced motion of particles and quasiparticles. The sun at 6000 K and the cold universe at 3 K, representing the most important renewable energy resource and the ultimate thermodynamic heat sink, are all accessible through thermal radiation.  The ability to control thermal radiation therefore plays a fundamentally important role in energy applications. Nanophotonic structures, where at least one of the structural features are at a wavelength or sub-wavelength scale, can have thermal radiation properties that are drastically different from conventional thermal emitters, and offer exciting opportunities for energy applications. In this talk, I will discuss recent developments of nanophotonic control in thermal radiation, and highlight some exciting energy application opportunities, including radiative cooling and energy harvesting systems.
