Scientists discovered that nanoscale wrinkles in 2D materials can preserve electron spin, enabling ultracompact and energy-efficient devices.

Researchers at CIC nanoGUNE BRTA and other institutes recently realized a spintronic device that leverages proximity effects alone, specifically a 2D graphene-based spin valve.

Electron spins in a bent 2D material interact with the flexoelectric effect created by the curvature of the sheet, which causes spin-up and spin-down electrons to split into distinct bands or regions.
