“…the lowest conduction band cause a strong contribution to the dielectric screening of the electron-electron interaction (EEI). While (for typical doping concentrations) this can be described by an additional Thomas-Fermi like contribution, 11,12,13 it does lead to a reduction of the quasiparticle band gap 14,15 and also of the exciton binding energy. 11,12,13 In addition, ionized-impurity scattering (IIS) reduces the quasiparticle band gap; 15 the sum of the EEI and the IIS contributions is called band-gap renormalization (BGR) in the following.…”

“…The method of solution of equation (9) has been described in reference [9] (see also, for example, Ref. [14]). The method uses the discretization in space and a conversion of differential equations into a set of linear algebraic equations.…”

“…Calculations of the optical properties are quite complicated since a separation of the center-of-mass motion and the relative motion is not possible, and one has to solve a complicated boundary problem in a 6-dimensional configuration space. Therefore various approximations have been proposed (for a review see, for example [1] and references therein).…”
