Cartoon illustration of the device design, where a thin hBN layer (blue) with selectively etched areas is used to avoid contact of the Pd electrodes (yellow) with the edges of the monolayer WTe2. The stack of graphite (gray)/hBN (blue)/monolayer WTe2 (red), shown in the cross-sectional view, is further stacked onto the bottom part with the electrodes, as indicated by the arrow. Inset: an image of device 1; the dashed red line highlights the monolayer edges and the white squares denote the contact regions. Image credit: Wang et al., doi: 10.1038/s41586-020-03084-9.
