The first band structures and calculated electronic properties of the compounds LaSe and LaTe are reported. The energy band structure of lanthanum monochalcogenides are obtained using the self‐consistent LMTO method within the atomic sphere approximation. The band structure outputs were used to calculate the physical properties such as the electronic specific heat, the Pauli paramagnetic susceptibility, and the superconducting transition temperature. The calculated results are compared with the available experimental values.
