TL;DR: In this article, the structure of the PL spectra observed at 4.2 and 77 K in the energy interval from 0.50 to 0.67 eV indicates that a considerable part of holes are trapped by deep and shallow acceptors before the interband recombi- nation with degenerate electrons occurs.
Abstract: Photoluminescence (PL) of n-InN grown by molecular beam epitaxy with Hall concentrations from 3.6 to 7.3 × 1017 cm–3 demonstrates dependences on carrier concentration, temperature, and excitation density which give evidences of a fast energy relaxation rate of photoholes and their equilibrium distribution over localized states. The structure of the PL spectra observed at 4.2 and 77 K in the energy interval from 0.50 to 0.67 eV indicates that a considerable part of holes is trapped by deep and shallow acceptors before the interband recombi- nation with degenerate electrons occurs. At room temperature, the band-to-band recombination of free holes and electrons dominates in PL. Experimental results on PL and absorption are described by model calculations under the assumptions of a band gap equal to 0.665–0.670 eV at zero temperature and zero carrier concentration and a non-parabolic conduction band with the effective mass at the G-point equal to 0.07 of the free electron mass.

TL;DR: In this paper, a generalized law of mass action was obtained for mixtures at a common temperature, without diffusion, and an equation for the ionization equilibrium was obtained which generalizes Sahas equation.
Abstract: A generalized law of mass action is obtained which reduces to the usual one when mixtures at a common temperature, without diffusion, are considered. An application to plasmas is performed and an equation for the ionization equilibrium is obtained which generalizes Sahas equation

TL;DR: In this article, the transfer of particles among free carrier (FC), bound exciton (BE), and free exciton photoluminescence (FE) states is studied.
Abstract: Free exciton (FE) and bound exciton (BE) photoluminescence (PL) of quantum well (QW) affected by free carrier (FC) is studied by a model which includes the transfer of particles among FC, FE, and BE states. It is shown that FC state is important not only at high temperature but also at low temperature. General formulas for FE and BE PL are developed. The two‐dimensional law of mass action is reproduced for high temperature, and the trapping of FE by defects is obtained for low defect concentration. Temperature behavior of FE and BE PL for high defect concentration is also discussed.

TL;DR: The incorporation of three-body collisions for dissociation/recombination into the Boltzmann equation is discussed in this paper, where conditions are assumed such that collisions are completed in the sense of scattering theory, so the collision operator is determined by scattering and reaction cross sections.
Abstract: The incorporation of three-body collisions for dissociation/recombination into the Boltzmann equation is discussed. Conditions are assumed such that collisions are completed in the sense of scattering theory, so the collision operator is determined by scattering and reaction cross sections. The resulting equation has anH-theorem, and the equilibrium solution requires the law of mass action in addition to the Maxwellian dependence on momentum. A brief discussion is given of the normal solution and the transport coefficients.

TL;DR: In this article, the authors investigated the equilibrium constant for dissociation to monomers in the classical approximation taking into account the limited number of bound and quasibounded pair states, and showed how the dimerization mass action law should be modified when thermal excitation is not negligible in comparison to the dissociation energy from the ground state.
