Dynamic Thermal Emission Control Based on Ultrathin Plasmonic Metamaterials Including Phase‐Changing Material GST (Laser Photonics Rev. 11(5)/2017)

Dynamic thermal emission control has attracted growing interest in a broad range of fields including radiative cooling, thermophotovoltaics and adaptive camouflage. Previous demonstrations of dynamic thermal emission control present disadvantages of either large thickness or requiring sustained electrical or thermal excitations. In this paper, an ultrathin plasmonic thermal emitter incorporating zero‐static‐power phase‐changing material Ge2Sb2Te5 (GST) is experimentally demonstrated to dynamically control thermal emission. The whole structure shows a total thickness of 550 nm (∼0.023λ), which is well below the subwavelength scale.
