Indeed, the electronic structure of a semiconductor is characterized by a conduction band (CB) and a valence band (VB) separated by a band gap of energy (Eg). From: Membrane Reactors for Energy Applications and
where ECB(k) and EN are the energy of the GaAs conduction band and the nitrogen resonant state, respectively. VCB,N is a parameter describing the coupling between the bands. Using this model, the dependence of E~ (which is the fundamental gap E0) and E+ with concentration can be modeled...

Total energy calculations Minimization of theground stateDFT total energy, with respect to small variations of the unit cell volume, allows us to find the structure equilibrium. We have reported that, besides the usual and system dependent underestimations of the local density approximation (LDA) to...
Zero of energy has been set at the valence band maximum. basis of phonon scattering15,26. After fitting the mobility curves in the high temperature range according to μ(T )~T −γ, γ has been found to be in the range of 2.1–2.4. These values of γ match well with those ...
. The energy splitting between ground states of bright and dark excitons (\({\Delta}_{{{\mathrm{DB}}}\)) and the conduction band spin–orbit splitting (\({\Delta}_{{{\mathrm{c}}}\)) are represented by the green arrows. Full size image The active part...
Fig. 4. a) UV–vis diffuse reflectance spectra of the as-prepared samples; b) Energy band gap evaluation from the plots of (Ahv)2 vs. the energy of the absorbed photon. The optical Eg of a crystalline semiconductor can be estimated by the formula of Ahv = (hv–Eg) n/2 [46]...
The scattering of phonons by electrons is calculated, assuming the usual electronphonon interaction, for a parabolic band whose degeneracy temperature is comparable with the temperature of the lattice. The contribution to the thermal resistance is given by an exact formula, subject only to justifiable...
