Oct 30, 2020 · In this work, we use band-structure engineering to create localized X + in monolayer WSe 2 which is interfaced with bilayer CrI 3. The type-II band alignment between the two materials promotes...

Jan 27, 2020 · By controlling the individual layer magnetization in CrI 3 with a magnetic field, we show that the spin-dependent charge transfer between WSe 2 and CrI 3 is dominated by the interfacial CrI...

Mar 29, 2019 · In this work, we take a van der Waals heterostructure to model the monolayer on the substrate and investigate the effects underpinning the valley splitting based on first-principles calculations.

Jun 2, 2021 · For the prototypical bilayer of WSe 2 on top of a ferromagnetic layer of CrI 3, we find substantially different coupling of both WSe 2 K-valleys to the sublayer. Besides an energy splitting of a few meV, the corresponding excitons have significantly different interlayer character with charge transfer allowed at the K̅ – point but forbidden at K̅ +.

Aug 9, 2024 · Here, we demonstrate an atomically thin spin-LED device based on a heterostructure of a monolayer WSe 2 and a few-layer antiferromagnetic CrI 3, separated by a thin hBN tunneling barrier. The...

Sep 13, 2024 · Our results show that the WSe 2 –CrI 3 heterostructure, acting as a p – n heterojunction, has advantageous capability in light detection, especially in self-powered light helicity detecting.

Apr 26, 2024 · Herein, we demonstrate the capability of inducing an ultrafast spin injection into a WSe 2 layer from a magnetic CrI 3 layer on a femtosecond time scale, achieved through real-time time-dependent density functional theory calculations upon a laser pulse.

May 14, 2019 · Here, using first-principles calculations, we investigate the electronic and magnetic properties of the van der Waals CrI 3 /WSe 2 heterostructures. We find that after forming heterostructures, monolayer CrI 3 undergoes a direct to indirect band gap transition and its gap size is greatly reduced.
