ab-initio calculations are employed to determine the structural, mechanical, elastic, electronic and thermodynamic properties of perovskite oxides XTcO3 (X = K, Rb). From the computed structural properties, KTcO3 and RbTcO3 are found to be stable with equilibrium lattice constants; 7.3943 Bohr and 7...
