On the Heat Equation for n-Type Semiconductors

Maria Mazzeo, Liliana Restuccia

Abstract


In a previous paper, in a geometrized framework for the description of simple ma-
terials with internal variables, the specific example of defective semiconductor crystals
defective by dislocations was considered and a dislocation core tensor `a la Maruszewski
and its flux were introduced as internal variables in the state space. Moreover, the entropy
function and the entropy 1-form, starting point to introduce a thermodynamical phase
space, were derived. In this contribution Clausius-Duhem inequality for these media is
exploited, and, using a Maugin technique, the laws of state, the extra entropy flux and the
residual dissipation inequality are worked out. Also, following Maugin, the heat equation
in a first and a second form is derived.
