In contrast to parabolic band model typically used in understanding electronic properties in general, thermoelectric and magneto-thermoelectric in particular, this study confirms non-parabolic band model results in better understanding of Seebeck coe

In this study the thermoelectric effect is investigated in terms of thermoelectric power, Figure of merit(ZT), and power factor. The calculations were carried out based on Boltzmann transport equation by taking ionized impurity scattering as a domina

In this paper electrical and thermal conductivity coefficients of heavily doped n-Silicon have been derived based on parabolic and modified density of states having band tails. The derivation uses Boltzmann transport equation with relaxation time ari
