Resumen
The PhD thesis is devoted to the complex study of the influence of cationic and anionic atoms substitution on thermodynamic properties of two-dimensional (Cu,Ag)+(In,Bi)3+P2(Se,S)6 and three-dimensional Sn(Pb,Ge)2P2S(Se)6 phosphorous chalcogenide crystals in a wide temperature range, and, especially, in the vicinity of the structural phase transitions by means of ac photopyroelectric calorimetry in the standard back-detection configuration.
