Crystal structure and exfoliation of nanowires. (a) Stereo-view of TNS bulk crystal structure projected along the c-axis. (b) The 4-blade “windmill” unit is highlighted from the bulk TNS structure. (c) Top view of a single ribbon extended along the c direction. (d) Optical image of exfoliated TNS nanowires under darkfield illumination (e) AFM image of the region marked by a dashed rectangle in (d) showing nanowires with 19 nm and 46 nm thickness. (f) AFM image of a thin nanowire with a thickness of approximately 7 nm.
