Thermodynamics of Extrinsic Semiconductors with Dislocations

Maria Paola Mazzeo, Liliana Restuccia


Since in nature there exist no ideal crystals without defects, the
aim of this paper is to contribute to describing the behavior of
deformable extrinsic semiconductors defective by dislocations using
a nonconventional model based on the extended irreversible
thermodynamics with internal variables developed in previous
papers, in which a dislocation density tensor à la Maruszewski and
its flux were introduced as internal variables. In this paper introducing a
geometric model we derive the entropy function and, exploiting the
Clausius -Duhem inequality by Maugin technique, we derive the laws
of state and the heat equation.
