SEM images of the CNT nanoelectrodes. (a) SEM images of a CNT electrode in the EBID process: (1) just after current breakdown; (2–5) after an EBID process of 2, 4, 6, and 10 min, respectively. (b) CNT electrodes with a series of gap sizes fabricated by the EBID method: (1–5). The left images are SEM images measured after the EBID process, the gap sizes are ca. 2, 4, 6, 8, and 10 nm, respectively, and the right images are SEM images measured before the EBID process. (c) SEM images of a nanoelectrode which is made of single-walled CNTs (1) before current breakdown, (2) before the EBID process, and (3) after about 2 min in the EBID process.
