TL;DR: In this article, the electronic structure and optical properties of RAlO 3 (R = Sm, Nd) have been investigated by full potential linearized augmented plane wave method within the framework of density functional theory in its generalized gradient approximation.

TL;DR: In this article, a back side, a front side opposite to the back side and a periphery portion of the substrate is formed by a pre-existing microstructure on the front side.

TL;DR: In this paper, the authors reported the characterization method and results of their ferroelectric lead zirconate titanate (PZT) thin film samples by areal laser scanning and demonstrated that monitoring the vibration of the surface area, rather than a single point as reported previously, could result in much more comprehensive and accurate information about the piezoelectric performance of the films.

TL;DR: In this article, the density functional theory calculations implemented in Vienna ab initio simulation package with generalized gradient approximation are performed to obtain the density of states (DOS) and the eigen vectors and eigen frequencies of vibrational modes of Ba2LaTaO6 (BLT) ceramic.

TL;DR: In this article, the authors used the full potential linearized augmented plane wave method and projector augmented wave method to investigate the ground state properties of EAO and obtained an indirect band gap of 1.8 eV with the valence band maximum at the Γ point and the conduction band minimum at the R point.
