Beyond van der Waals: Next Generation of Covalent 2D-2D Heterostructures

A team of scientists at IMDEA Nanociencia have velcroed 2D structures of MoS2 and graphene using a covalent connection for the first time. The 2D-2D structures were used to build robust field effect transistors with controlled electronic communication, interface chemical nature and interlayer distance. The electronic properties of the system are dominated by the interface of the two covalently bonded layered materials.
