This program aims to exploit extraordinary new scientific opportunities enabled by designing van der Waals (vdW) heterostructures that allow creation of novel functional materials with unprecedented flexibility and control. The key innovation here is that van der Waals bonded materials with different dimensionality and wide-ranging properties can be integrated together to form a new class of materials – vdW-bonded heterostructures – in which each constituent can be engineered separately. Such vdW heterostructures represent new artificial quantum materials that do not exist in nature.
