Electrical Control and High-Bias Enhancement of Magnetoresistance in van der Waals Antiferromagnetic Spin-Filter Tunnel Field-Effect Transistor

Gaurab Samanta, Neeraj K. Rajak, Dorye L. Esteras, Paul Noël et autres

We report a vertical spin-filter tunnel field-effect transistor (Spin-TFET) based on the air-stable van der Waals antiferromagnet CrSBr, integrated in a graphite/hBN/graphene/CrSBr/graphene heterostructure. Electrostatic gating enables direct electrical tuning of the spin-filter tunneling magnetoresistance (MR) over a wide range, from ∼100% to …
