説明:

(abstract)

As a crucial parameter in the determination of thermal conductivity, the heat capacity of Cu2+xZn1-xSnS4 (CZTS) has been investigated and analyzed in detail from 2 to 773 K. The effects of the Cu-Zn stoichiometric ratio and phase transition have been quantified and correlated with entropy variation. We confirm that the compounds follow the Dulong-Petit approximation above the Debye temperature θD and solve literature discrepancies on CZTS. The in-depth low-temperature heat capacity analysis revealed an approximate image of the energy dependance of the phonon density of state in kesterite which agrees with results of first-principles calculations.
