Figure 1. Ferromagnet|Hexagonal Boron Nitride-Graphene van der Waals heterostructure spin transport devices.

Figure 1

(a) Schematic representation of the h-BN|graphene van der Waals heterostructures (vdWH) with multiple ferromagnetic (FM) contacts for spin injection and detection in nonlocal geometry. The magnified view of the contacts exemplifies different thicknesses of h-BN barriers under the high resistance (HR) injector and low resistance (LR) detector. (b) Optical microscope image (color enhanced) of a fabricated multi-terminal spin transport device showing a heterostructure of a graphene flake covered by a CVD h-BN tunnel barrier and multiple ferromagnetic Co electrodes.
