Buckling characterization of vertical ZnO nanowires using nanoindentation

Nanomechanical characterization of vertical well-aligned single-crystal ZnO nanowires on ZnO:Ga/glass templates was performed by nanoindentation technique. The buckling loads were found to be 1465 and 215 μ N for the ZnO nanowires of 100 and 30 nm diameters, respectively. Furthermore, the buckling e...

Description
Summary:Nanomechanical characterization of vertical well-aligned single-crystal ZnO nanowires on ZnO:Ga/glass templates was performed by nanoindentation technique. The buckling loads were found to be 1465 and 215 μ N for the ZnO nanowires of 100 and 30 nm diameters, respectively. Furthermore, the buckling energies for the ZnO nanowires of 100 and 30 nm diameters were 3.62 × 10 − 10 and 3.69 × 10 − 11 J , respectively. Based on the Euler buckling model, Young's modulus of the individual ZnO nanowire has been derived from two possible modes in this work.
