Twistronics

A way to engineer electronics devices by twisting layers of graphene material properties change to allow for superconductivity at room temperature.

Researchers at Columbia University in the US developed a device structure in which they can vary the "twist" angle between layers of 2D materials (such as graphene) and study how this angle affects their electronic, optical and mechanical properties. The measurements are carried out on a single structure rather than multiple ones.



Achieving this variety of electronic properties in conventional materials normally requires changing their chemical composition. The ability to vary the electronic property of a 2D material simply by altering the twist angle between its layers is therefore a new direction in device engineering.
