Extended Thermodynamics of Charge Carrier Transport in Semiconductors

Abstract

According to the methods of extended thermodynamics, we find a set of balance equations for the determination of the fields m ^α (mass density), V ^α _k (velocity), ε ^α (specific internal energy), m^α _<ij> (stress deviator), q ^α _i (heat flux), E _i (electric field), B _i (density of magnetic flux); the index α (and every other greek index) indicates that the quantity considered is referred to the lattice (for α = 0), to electrons (for α = 1) and to holes (for α = 2). In these balance equations some constitutive functions appear; restrictions on their generality are found by imposing the entropy principle and that of material objectivity.
