Harnessing Graphene's Potential: Programming Twist Angles and Strain Profiles in 2D Materials

Researchers are exploring the potential of twistronics, a field in condensed matter physics, by manipulating the properties of 2D materials like graphene through subtle changes in the twist angle between stacked layers. A new fabrication technique using long ribbons of graphene allows for better control over the twist angle and strain, leading to more predictable and reproducible devices. This technique opens up possibilities for studying the fundamental properties of twisted layers of graphene and other 2D materials, and may help uncover the origins of phenomena like superconductivity at specific twist angles.
