Abstract :
The band theory of solids is capable of explaining such fundamental properties of electronic semiconductors as the dependency of specific resistance on impurity content, the negative temperature coefficient of resistance, the sign of the Hall and thermoelectric effects, and the direction of rectification. Measurements of the specific resistance and the Hall constant enable the calculation of density, mobility, and mean free path of the electric carriers as a function of temperature and impurity.
