Maximal violation of Kirchhoff's law in planar heterostructures
Lu Wang, F. Javier Garcı́a de Abajo, Georgia T. Papadakis
Abstract
The ultimate energy-harvesting efficiency (93%) is made possible by violating Kirchhoff's law of radiation. Using a planar nonreciprocal structure, a complete violation of Kirchhoff's law can be achieved. In addition, this planer structure does not require any coupling beyond the light cone.
