Nanostructured materials exhibit superior physical and mechanical properties, and they hold great promise for enabling the development of novel micro/nano electro-mechanical systems. A fundamental understanding of the mechanical deformation and degradation in nanostructured materials is critical for designing the damage-tolerant nanostructures and devices. The in situ transmission electron microscopy...
ZnO nanotetrapods, ZnO nanowires and Zn nanowires were fabricated by the vapor deposition process at the different flow rates of the carrier gas (N 2 ). Further oxidation of the Zn nanowires led to the formation of ultra-fine ZnO nanoneedles. Photoluminescence (PL) spectra of ZnO nanocrystals exhibited a deep-level emission in the visible region and a near-band-edge emission in the ultraviolet...
