Electronic materials with nanoscale curved geometries

As the dimensions of a material shrink from an extended bulk solid to nanoscale structure, size and quantum confinement effects become dominant, altering properties material. Materials with curved geometries, such as rolled-up nanomembranes zigzag-shaped nanowires, have recently been found exhibit number intriguing electronic magnetic due shape-driven modifications charge motion or effects. Local strain generated by curvature can also lead changes in electromechanical coupling. Here we review development materials geometries. We examine origin shape-, confinement- strain-induced explore how exploit these electronic, spintronic superconducting devices. consider methods required synthesize characterize curvilinear nanostructures, highlight key areas for future electronics. This Review examines geometries explores
