Self-consistent thermodynamic description of a nonmetallic nonferromagnetic solid (using silicon as an example)

An algorithm is developed for constructing a self-consistent thermodynamic model of the Debye type to simultaneously describe the temperature dependences of the entire complex of the basic thermal properties of a nonferromagnetic nonmetallic isotropic solid. Silicon is used as an example to demonstrate that, even within simplified model assumptions about the values of thermodynamic parameters, it is possible to make a very satisfactory self-consistent description of thermodynamic parameters of a solid in a wide temperature range of many hundreds of Kelvins.
