An approach to device engineering in which the twist angle between layers of 2D materials such as graphene affects their electronic, optical and mechanical properties.
Researchers at Columbia UniversityColumbia University in the US have developed a new 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, which are carried out on a single structure rather than multiple ones (as was the case before), could advance the emerging field of "twistronics" - a fundamentally new approach to device engineering.
