摘要:
Multiferroic van der Waals (vdW) heterostrucutres offer an exciting route toward high-performance nanoelectronics and spintronics device technology. Here we investigate the electronic and transport properties of multiferroic vdW heterostructures composed of a ferromagnetic FeCl2 monolayer and a ferroelectric Sc2CO2 monolayer using first-principles density functional theory and quantum transport simulations. We show that FeCl2/Sc2CO2 heterostructure can be reversibly switched from semiconducting to half-metallic behavior by electrically modulati...
