Abstract
The University of Central Florida invention describes a proof-of-concept of a method to tune the spectrally selective thermal emission from nanopatterned graphene (NPG). This is done by means of a gate voltage that varies the resonance wavelength of localized surface plasmons (LSPs) around the circular holes that are arranged in a hexagonal or square lattice pattern in a single graphene sheet in the wavelength regime between 3 µm and 12 µm. By generalizing Planck’s radiation theory to grey-body emission, the thermal emission spectrum can be tuned in or out of the two main atmospheric transparency windows of 3 to 5 µm and 8 to 12 µm in the mid-IR regime. It can also be tuned in or out of the opaque mid-IR regime between 5 and 8 µm.
