Abstract
A light-emitting device includes a substrate including a photonic cavity and configured to function as a gate, an active layer including a two-dimensional material, a first conductive contact, and a second conductive contact. The wavelength range of light generated by the light-emitting device may be narrowed based on the photonic cavity being included in the substrate, and the intensity and wavelength range of the generated light may be controlled based on the substrate functioning as a gate.
