Some Basic Facts on Semiconductors,tant material as far as commercial applications of semiconductors are concerned. However, while silicon satisfies most of our current needs for electronics, it is only of limited use for optoelectronic applications. Semiconductor lasers, which are at the heart of compact disc players (present in mos

Interaction of Matter and Electromagnetic Fields,the resulting currents give rise to electromagnetic fields via the . . In turn, these fields lead to an interaction between the particles. For a closed system that is isolated from the outside world, these interactions can be completely incorporated into the equations of motion of charged particl

One-Particle Properties,miltonian, as introduced in the last chapter, would be an unambigous condition for proceeding further. Indeed, there are many experimental data, ranging from ground-state properties to response functions, which can be directly related to this information. But, apart from the problem that there is no

Uncorrelated Optical Transitions,As typical photon wave vectors are negligible with respect to the extent of the Brillouin zone, the photon looks practically like a vertical line in the energy dispersion diagram... (Fig. 4.1a,b), . (Fig. 4.Id) and similarly ., and . (Fig. 4.If) directly connect an occupied initial state (filled cir

Correlated Transitions near the Band Edge,tion among carriers. If optical transitions take place in the vicinity of the . point of the Brillouin zone, we can assert that the effective-mass approximation is valid, which allows us to analyze optical transitions in a small part of the Brillouin zone with very high accuracy. In real space, this

,Nonequilibrium Green’s Functions,This is due to the direct Coulomb interaction among carriers and the mediated interaction via phonons. So far, the theoretical approaches that we have developed to tackle this difficult problem have all been based on the . approach and — apart from the χ. expansion in the last chapter — on the Hartr
