How are Van der Waals Heterostructures Fabricated?
The fabrication of van der Waals heterostructures typically involves mechanical exfoliation or chemical vapor deposition (CVD). In mechanical exfoliation, individual layers are peeled off from bulk materials and then stacked manually. CVD, on the other hand, allows for the growth of high-quality 2D layers on a substrate. Once the layers are prepared, they can be stacked using a dry transfer technique to form the heterostructure.
