Molecular electronics: connection across nano-sized electrode gaps

摘要

Prefabricated nanoscale structures in which gold electrodes are separated by an insulating core permit self-assembly of a single string "molecular necklace" around its circumference; these devices require no further invasive metal deposition following molecular insertion and exhibit symmetrical current-voltage (Ⅰ-Ⅴ) curves that mimic those of self-assembled films on planar substrates.
