Investigation of some mechanisms for formation of exciton absorption bands in layered semiconductor n-InSe and p-GaSe crystals

We show that processes of creation, radiation and decay of the ground (n = 1) and excited exciton states in layered n-InSe and p-GaSe crystals involve direct (photon -> exciton -> photon, at k = 0), as well as indirect vertical (photon ± phonon -> exciton -> photon ± phonon, at k ~0), op...
