This work employs nanoskiving to fabricate free-standing NiTi nanowires. Nanoskiving, a recently-developed nanofabrication method, has generated nanowires of pure metals and this work demonstrates the first successful generation of metallic alloys. Nanoskiving takes advantages of well-developed NiTi thin film technology and complements with ultramicrotomy for thin sectioning into nanowires. Nanoskiving offers a novel pathway for fabrication and handling of free-standing shape memory alloy nanowires. The generated nanowires are characterized in scanning electron microscopy for the intact continuity and yield, in atomic force microscopy equipped with temperature capability for the sectioning-mechanism related surface morphology, and in transmission electron microscopy with a cooling holder for the crystal structure and microstructure connecting to shape memory response. The ability of producing NiTi nanowires with precise composition, continuity and high yield, controllable surface morphology, and transformable crystal structure, enables the enrichment of shape memory smart materials into nanoscale regime for one-dimension fundamental research and applications.
