How Perfect Can Graphene Be?

(PhysOrg.com) -- Physicists have investigated the purest graphene to date, and have found that the material possesses unprecedented high electronic quality. The discovery has raised the bar for this relatively new material, ...

Layer-engineered large-area exfoliation of graphene

Large-scale manufacturing processes that aim to produce two-dimensional materials (2DMs) for industrial applications are based on a competition between quality and productivity. The top-down mechanical cleavage method allows ...

Express tool for graphene quality control

The National Physical Laboratory (NPL) has collaborated with Chalmers University of Technology and Linköping University in Sweden to help develop a fast and inexpensive tool for quality control of graphene grown on silicon ...

Colloidal dispersions of nanosheets for catalysis

Researchers from the ICN2 Nanostructured Functional Materials Group, in collaboration with other institutions, have used a liquid phase exfoliation process to obtain nanosheets with enhanced electrocatalytical properties. ...

Printable two-dimensional superconducting monolayers

Highly crystalline 2-D transition metal dichalcogenide superconductors and their associated (van der Waals) heterostructures provide a rich platform for the investigation of new quantum physics and exotic superconductivity. ...
