The diverse family of layered van der Waals (vdW) materials includes metals, semiconductors, insulators, and many materials hosting exotic phases of such as superconductivity, charge density waves, and topological states. The isolation of graphene in 2005 opened up the possibility of thinning all of these materials down to individual atomic sheets.
IRG1 studies van der Waals heterostructures created by vertical stacking of 2D materials, using heterostructures to understand the properties of 2D materials in the intrinsic limit, and to achieve new emergent properties at interfaces. In five years, the IRG1 team has completed research on robust electrical contacts, inert-atmosphere assembly, measurement of electronic and optical properties of 2D materials in the intrinsic limit, and observation of new interfacial phenomena.
The IRG1 team has also begun to research a number of entirely new research directions, and is currently focusing on topics such as the synthesis of crystalline 2D semiconductors and magnetically doped topological insulators, rotatable heterostructures, exfoliation and assembly at macroscopic dimensions, and new topological phenomena.
