“…From the technological point of view, perovskites have emerged as the most promising candidates for optoelectronic, magnetic, and energy applications [1,2]. Perovskites are represented by the general formula ABX 3 , where A (located at the corners) and B (located at the center) are cations, and X is an anion such as halogen, chalcogen, and pnictogen (situated at the faces of the unit cell).…”

Over the last two decades, perovskites have attracted researchers’ attention due to their fascinating physical properties for different components in the electronic industry. Here, we have investigated the electronic structure and thermoelectric properties of KPdX3 (X = F, Cl, Br, I) perovskites using Density Functional Theory (DFT). Initially, the structure of all the compounds was relaxed, and the optimized lattice parameters were obtained using the PBE functional. The phonon dispersion spectrum obtained for all compounds indicated a dynamically stable nature for these perovskites. The analysis of the electronic band structure showed metallic nature for KPdX3. The calculated elastic properties offer elastic stability and ductility for KPdX3. The appropriate values of thermoelectric parameters show the potential of these KPdX3 for thermoelectric applications. Moreover, the thermoelectric performance of these compounds can be further improved by tuning the thermal conductivity of the series by selecting an appropriate cation as a dopant. The thermoelectric properties of KPdX3 can guide future experimental and theoretical studies.
