Journal ArticleDOI

First-principles study of ferroelectric and antiferrodistortive instabilities in tetragonal SrTiO 3

TL;DR: In this article, the authors carried out first-principles density-functional calculations of the antiferrodistortive (AFD) and ferroelectric (FE) soft-mode instabilities in tetragonal ground states with the structural degrees of freedom treated in a classical, zero-temperature framework.
Journal ArticleDOI

Period-doubled structure for the 90 partial dislocation in silicon

TL;DR: In this paper, the authors suggest that the commonly accepted core structure of the 90 − partial dislocation in Si may not be correct, and propose instead a period-doubled structure.
Journal ArticleDOI

Effective J = 1 / 2 Insulating State in Ruddlesden-Popper Iridates: An LDA + DMFT Study

TL;DR: It is demonstrated that the deviation from the ideal Jeff=1/2 state is negligible at short time scales for both single- and double-layer iridates, while it becomes quite significant for Sr3Ir2O7 at long times and low energy.
Journal ArticleDOI

Fast molecular-dynamics simulation for ferroelectric thin-film capacitors using a first-principles effective Hamiltonian

TL;DR: In this paper, a fast molecular dynamics method is applied to ferroelectric thin-film capacitors with short-circuited electrodes or under applied voltage, and it is shown that dead layers (or passive layers) between ferroelectrics and electrodes markedly affect the properties of capacitors.
Journal ArticleDOI

Structural, electronic, and dielectric properties of ultrathin zirconia films on silicon

TL;DR: The as-deposited films reported in this paper appear amorphous below a critical thickness (∼5.4nm) and transform to a predominantly tetragonal phase upon annealing.
