InSe as a case between 3D and 2D layered crystals for excitons

InSe as a case between 3D and 2D layered crystals for excitons

The optical properties of layered InSe aren’t fully understood. Here, the authors observe the exciton, biexciton, and P-band of exciton-exciton scattering in the photoluminescence spectrum of InSe, and calculate an exciton binding energy value of ≥20 meV, markedly higher than the currently accepted...
