Hybrid $\mathbf{k}\cdot \mathbf{p}$-tight-binding model for intersubband optics in atomically thin InSe films

Samuel J. Magorrian, Adrian Ceferino, Viktor Zólyomi +1

We propose atomic films of n-doped $\gamma$-InSe as a platform for intersubband optics in the infrared (IR) and far infrared (FIR) range, coupled to out-of-plane polarized light. Depend…
