New method of transport measurements on van der Waals heterostructures under pressure
نویسندگان
چکیده
The interlayer coupling, which has a strong influence on the properties of van der Waals heterostructures, strongly depends distance. Although considerable theoretical interest been demonstrated, experiments exploiting variable coupling nanocircuits are scarce due to experimental difficulties. Here, we demonstrate novel method tune using hydrostatic pressure by incorporating heterostructure based in piston-cylinder cells with dedicated sample holder design. This technique opens way conduct transport measurements nanodevices under up 12 contacts without constraints at fabrication level. Using measurements, that hexagonal boron nitride capping layer provides good protection heterostructures from medium, and show evidence weak localization TMDC/graphene heterostructure.
