Two-dimensional (2D) materials, in general, allow the realization of unique quantum phenomena unattainable in the common three-dimensional (3D) world. A prime example is graphene. Transition metal dichalcogenides (TMDs) have a similar structure. Both can be stacked to form van der Waals heterostruct ures or can be exfoliated into single layers. But TMDs have an extra variety of excellent properties, including strong spin-orbit coupling and superconductivity. ...read more read less
