TL;DR: In this article, the authors studied tunnelling through thin ferromagnetic chromium tribromide (CrBr3) barriers that are sandwiched between graphene electrodes, which could allow two-dimensional spintronic devices to be developed.

TL;DR: In this article, electron tunnelling through a thin (2-6 layers) ferromagnetic CrBr3 barrier has been investigated theoretically and experimentally, which has been used to study the electronic states both in the tunneling barrier and in the emitter and collector contacts.
Journal ArticleDOI
Oxygen-vacancy driven electron localization and itinerancy in rutile-based TiO 2
TL;DR: In this paper, a charge self-consistent combination of density functional theory (DFT) with dynamical mean-field theory (DMFT) was proposed to solve the problem of oxygen deficiency in titanium dioxide.
Journal ArticleDOI
Quantum many-body intermetallics: Phase stability of Fe 3 Al and small-gap formation in Fe 2 VAl
TL;DR: In this paper, the phase stability of a bcc-based Fe-Al system was investigated based on a combination of density functional theory with dynamical mean-field theory in a charge self-consistent manner.
Journal ArticleDOI
Role of nonspherical double counting in DFT+DMFT: Total energy and structural optimization of pnictide superconductors
TL;DR: In this article, a simple scheme for avoiding nonspherical double counting in the combination of density functional theory with dynamical mean field theory (DFT+DMFT) is developed for total energy calculations and structural optimization of the pnictide superconductor LaFeAsO.
