Abstract

AbstractThe effective medium theory is extended to the calculation of the dc conductivity and Hall effect of macroscopic inhomogeneous semiconductors in high (just after ohmic region) electrical fields. A cubic network of the macroscopic barriers with random heights is used as a model of the considered semiconductors. The electrical field dependences of the direct and Hall current densities are calculated. As it follows from calculations on the direct and Hall current differential conductivities and also the Hall angle decrease with increasing electrical field in the non‐ohmic region.
