Wannier Function and Effective Mass Approximation, potential. In the presence of an external force ., an electron is accelerated in . space in the form of . = .. The electron motion is then expressed in the classical picture of a particle with the effective mass .. or 1/.. = (1/..)... .. and the momentum . = . = ..〈.〉. The results are used to derive transport properties in Chap. 6.

Magnetotransport Phenomena, can deduce phonon energy involved with the magnetophonon resonance. These two oscillatory magnetoresistance effects are very widely used to investigate semiconductor parameters. Quantum Hall effect is not dealt with here but discussed in detail in Chap. 8.

Cyclotron Resonance and Energy Band Structures,bands. The non-parabolicity of the conduction band is also discussed. Quantum mechanical treatment of the electrons in the conduction band and holes in the valence bands leads us to draw the picture of Landau levels which is used to understand magnetotransport in Chap. 7 and quantum Hall effect in Chap. 8.

Cyclotron Resonance and Energy Band Structures,bands. Electrons are subject to rotational motion in a magnetic field (cyclotron motion) and resonantly absorb the radiation fields (microwaves or infrared radiation) when the cyclotron frequency is equal to the radiation frequency. The resonant condition gives the effective mass of the electron. An

Optical Properties 1,Maxwell’s equations. Then quantum mechanical derivations of direct and indirect optical transition rates are given in addition to the classification of the joint density of states. Optical transitions associated with electron–hole pair, excitons, are also discussed. Dielectric functions are discusse
