Figure 4.

CTEM images showing two representative ZnO NWs (a, b). Extracted from unirradiated and irradiated (fluence = 1017 cm−2) areas, respectively. The insets of both figures show the nanowire tip details; note that the irradiated NW tip is faceted as a consequence of the strike by Ar+ energetic particles.
