Controlling heat flow in a solid by switching crystal structure dimensionality

Researchers developed a material in which heat flow can be dynamically controlled by changing its thermal conductivity. The thermal conductivity is modulated by reversibly switching between a two-dimensional and a three-dimensional crystal structure in a solid solution of lead selenide and tin selenide, opening doors to potential thermal management applications.

Beyond van der Waals: next generation of covalent 2D-2D heterostructures (w/video)

A team of scientists have velcroed 2D structures of MoS2 and graphene using a covalent connection for the first ime. 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.
