Theoretical Investigation of Heat Capacities as a Function Temperature of Stannous Selenide (SnSe) Using Einstein-Debye Approximation

A new alternative approach has been suggested for evaluating the heat capacities of stannous selenide (SnSe), based on Einstein-Debye approximation. It is well known thermal behavior solids a very important theoretical problem that explored thoroughly with development Einstein, Debye and recently developed approximations. Many additional thermophysical characteristics materials may be analyzed using employed in this study. As an application, have computed by method SnSe temperatures range between 40 900 K. The temperature dependence found to good accord literature throughout wide range.
