Perovskite-related ReO3-type structures [PDF]

Nature Reviews Materials, 2020
Materials with the perovskite ABX3 structure play a major role across materials chemistry and physics as a consequence of their ubiquity and wide range of useful properties. ReO3-type structures can be described as ABX3 perovskites in which the A-cation site is unoccupied, giving rise to the general composition BX3, where B is typically a cation and X ...

Defect Structure of Nonstoichiometric Perovskite [PDF]

Japanese Journal of Applied Physics, 1989
The Po2 dependance on electrical conductivity and the oxygen diffusion in non-stoichiometric BaTiO3 and (Ba, Ca) TiO3 ceramics were investigated. It is confirmed that the electrical conductivity of A-site-excess specimen at high temperature is decreasing with decrease of oxygen pressure.

d0 Perovskite-Semiconductor Electronic Structure

, 2010
We address the low-energy effective Hamiltonian of electron doped d0 perovskite semiconductors in cubic and tetragonal phases using the k*p method. The Hamiltonian depends on the spin-orbit interaction strength, on the temperature-dependent tetragonal distortion, and on a set of effective-mass parameters whose number is determined by the symmetry of ...

In-situ growth of low-dimensional perovskite-based insular nanocrystals for highly efficient light emitting diodes

Light: Science & Applications, 2023
Regulation of perovskite growth plays a critical role in the development of high-performance optoelectronic devices. However, judicious control of the grain growth for perovskite light emitting diodes is elusive due to its multiple requirements in terms ...

Competing Structural Instabilities in Cubic Perovskites [PDF]

Physical Review Letters, 1995
We study the antiferrodistortive instability and its interaction with ferroelectricity in cubic perovskite compounds. Our first-principles calculations show that coexistence of both instabilities is very common. We develop a first-principles scheme to study the thermodynamics of these compounds when both instabilities are present, and apply it to SrTiO$
