Figure 3
(a) Rotation angles of the three orthogonal lattice planes (0002) (squares), (triangles) and (circles) in ZnO NW I during three-point bending. The inset shows the crystalline orientation of the NW with its growth direction along [0001] lying flat on one of its side facets. (b) The ZnO Laue spot before and after the three-point bending test, demonstrating that no plasticity was actually induced within the probed volume. |
