Abstract
To apprehend the electronic structures and related physical quantities such as Fermi surface, and optical properties of the perovskite LaPdO3 system, we employed the full potential linearized augmented plane wave method. The existence of rare-earth (La) and the actinide element (Pd) has implied to include the Hubbard correction and spin-orbit coupling. We reported the electronic density states calculations and the related optical properties as well as the Fermi surface. The near-Fermi valence bands are mainly composed of La-p/d states and show a substantial overlapping with the conduction band, proving a metallic nature of the perovskite. The Fermi surfaces, comprises of the disconnected electronic-like pockets and hole-like pockets situated around Z. The optical properties were also discussed to complete the optoelectronic structure description. (C) 2019 Elsevier B.V. All rights reserved.
