A new twist on 'magic-angle' graphene: Tuning resistance with strain
Phys.org ·
The Brief · written from 2 sources
- Researchers report giant elastoresistance in magic-angle twisted bilayer graphene, where strain changes electrical resistance.
- The study was published in Science, volume 394, issue 6825, pages 768-772, in November 2026.
- Experiments in this field use robotic manipulators to stack and twist two single-atom-thick carbon sheets.
Why it matters
Showing that strain can tune resistance in magic-angle graphene offers a new way to control its electronic behaviour, which matters for researchers studying correlated and superconducting states in 2D materials.

In materials science labs around the world, researchers regularly reproduce a peculiar experiment. Under a microscope, they use tiny robotic manipulators to lay two sheets of carbon, each a single atom thick, against one another. They then rotate the top sheet against the bottom…
