In this paper, we calculate the luminescence of the dilute quaternary InAs(N,Sb). The incorporation of N\ud leads to a reduction of the energy gap of the host InAs and Sb acts as a surfactant, improves the N incorporation and\ud further reduces the b

In this paper we introduce analytical solutions of interband polarization, which is the self-energy of the Dyson equation for the photon Green’s functions, and apply them to studying photoluminescence of Coulomb-correlated semiconductor materials.

In this paper, we calculate the luminescence of the dilute quaternary InAs 1−x−y N x Sb y semiconductor using a microscopic approach. The theory starts with the band anticrossing model applied to both conduction and the valence band to generate i

This paper delivers an approximation to the complex many body problem of luminescence in semiconductors to the case of mid infrared luminescence of dilute nitrides. The results are compared with recent experimental data for InAsN semiconductors.

In this paper, analytical expressions for optical nonlinearities are applied in the simulations of the absorption and photoluminescence of mid infrared materials. The fast and efficient approximations reproduce recent experimental data for dilute nit
