SEM images of cross section of Al films deposited on the substrate maintained at at deposition angles of (a) 85°, (b) 73°, and (c) 58°. The arrows indicate the incident direction of Al vapor. Magnified images of the nanorods indicated by an asterisk are shown in Fig. 2.
SEM images of [(a)–(c)] nanorods and (d) nanowires of Al. (a) and (b) show magnified images of the nanorods indicated by an asterisk in Fig. 1(a). The images shown in (c) and (d) were obtained in a region different from that shown in Fig. 1(a) in the same sample. The incident direction of Al vapor was from the right to the left.
SEM images of samples deposited at (a) and (b) .
