摘要
An electrically controllable and tunable electromagnetic-field absorber/thermal emitter is invented using graphene/two-dimensional materials based multilayer nanostructures that have the absorption efficiency of unity at mid-infrared wavelengths. Alternating layers of graphene and hexagonal boron nitride are deposited between support materials and grown on a substrate. Tungsten may be used as the substrate, and silicon carbide as the support material; or, silicon may be used as the substrate and tungsten disulfide as the support material depending on the operating frequencies and ambient temperature. The invention demonstrates a selectable, tunable and switchable electromagnetic-field absorption or thermal emission by changing a DC bias that alters the chemical potential of the graphene layers and thereby the optical response of the multilayer nanostructures.
