| Özet |
| In this study, a complete analytical method of the evaluation and temperature behavior of the Lorenz number for non-degenerate and degenerate semiconductors has been proposed. Based on the quantum theory of kinetic effects, the Lorenz number formula of semiconductors in terms of two parameter Fermi functions has been formulated analytically. In spite of the long history of thermoelectric effect and its significant role in semiconductor phenomena, the analytical studies of two parameter Fermi function are very limited in the literature. By using an efficient algorithm for the calculation of two parameters Fermi function, the temperature dependence of Lorenz number has been evaluated analytically. The suggested method is useful for determination of Wiedemann-Franz law that provides connection between the thermal and electrical conductivity which is important for thermoelectric materials. |
