Correlated one-dimensional electron conduction in ferroelastic domain walls through nematic-like charge stripes

One-dimensional electronic transport reveals many-body quantum phenomena and serves as a foundation for quantum devices, sensors, and reconfigurable electronics. Here, we demonstrate that surface-exposed ferroelastic twin walls in epitaxial WO 3 films function as intrinsic one-di...

Instability-Driven Mechanically Locked States in Functional Oxide Membranes

Abstract While mechanical instabilities enable engineered nonlinear responses, their controlled application in functional crystalline oxides has remained largely unexplored. Recent advances in freestanding oxide membranes now allow their integration into nanoscale, bistable archi...
