    Abstract

    We propose atomic films of n-doped γ-InSe as a platform for intersubband optics in the infrared and far-infrared range, coupled to out-of-plane polarized light. Depending on the film thickness (number of layers) and the amount of n-doping of the InSe film, these transitions span from ∼0.7 eV for bilayer to ∼0.05 eV for 15-layer InSe. We use a hybrid k·p theory and tight-binding model, fully parametrized using density-functional theory, to predict their oscillator strengths and thermal linewidths at room temperature.
