What to know about Graphene nanowrinkles could reshape electricity in future ultrathin devices

Researchers from Rice University and other institutions have demonstrated that sub-nanometer wrinkles in graphene can alter its electrical properties through a phenomenon called flexoelectricity. The study, published in Advanced Materials, suggests that controlling the geometry of atomically thin materials could lead to the development of more sensitive sensors and ultrathin electronic devices.

What happened

Graphene nanowrinkles could reshape electricity in future ultrathin devices Robert Egan Senior Editor Rice University researchers have shown that tiny wrinkles in graphene can change the material's electrical properties, providing evidence for…

Why it matters

The findings are published in Advanced Materials.

Common ground

The discovery suggests scientists may be able to control electricity in atomically thin materials by changing their shape instead of adding new chemicals or materials.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
