Figure 4
Mechanical stability of ZnO nanorods and nanosheets.
a, Load-displacement curve of ZnO nanosheets and nanorods using nanoindentor. Nanoindentation testing gives insight into the ZnO nanorods and nanosheets which respond differently under uniaxial compression. b–d and e–g, Schematic images describing the morphological development of ZnO nanorods and nanosheets, respectively, according to the applying load of below and above Pcrt.
