Characteristics of Progressive Damage of ZnO Nanowires during
Contact Sliding under Relatively Low Loads
Figure 6
SEM image of ZnO nanowire fractured in (a) parallel to the (0001) plane after 3 cycles under 6 mN applied load and (b) both parallel and nonparallel to the (0001) plane after 10 cycles under 6 mN applied load. Dotted lines show the fractured plane of the ZnO nanowires. (0001) is the perpendicular plane to the c-axis of ZnO crystal that represents the growing direction of ZnO nanowires.
