Title
The Magical Things of Nanotechnology: from the Darkest Material to a Super-Planckian Radiation
Speaker
林尚佑 教授 (美國壬色列理工學院物理學、應用物理學和天文學系) Prof. Shawn-Yu Lin (Department of Physics, Applied Physics and Astronomy, Rensselaer Polytechnic Institute)Abstract
The field of nano-photonics and in particular, photonic-crystal, has become one of the most influential and wide-ranging realms of contemporary electro-magnetism and optics. In this talk, I will review two recent advances in random and periodic nanostructures, respectively. The first is the creation of the darkest artificial material on earth, having a world-record absorptance of 99.97%1,2. The second is the striking discovery of super Planckian thermal radiation in a 3D metallic photonic-crystal at elevated temperatures 3,4.
