Single-crystal nanocastles of ZnO

As a result of switching the growth from hexagonal disks to nanorods/nanobelts, single-crystalline ‘nanocastles’ of ZnO have been synthesized. This new structure was constructed by two basic parts: a sheet-like hexagonal crystal base and vertical nanorods/nanobelts surrounding the base as the ‘walls’ of the castle. Moreover, for the first time, ZnO nanorods with a triangular and diamond cross-s...

Mechanical deformation of single-crystal ZnO

The deformation behavior of bulk ZnO single crystals is studied by a combination of spherical nanoindentation and atomic force microscopy. Results show that ZnO exhibits plastic deformation for relatively low loads ~*4–13 mN with an ;4.2 mm radius spherical indenter!. Interestingly, the elastic–plastic deformation transition threshold depends on the loading rate, with faster loading resulting, ...
