ABSTRACT

The Theoretical study of the structural, electronic and mechanical properties of KHfO3 was analysed using the first principle calculations with different exchange functional.

  In this study calculations were performed using the density functional theory implemented in the QUANTUM ESPRESSO codes.

 All of  these compounds’ lattice constants are optimally optimized.

This study’s findings were compared to experimentally findings and other works.
