| 英文摘要 | A simple thermally lithographic method for fabricating nanowire-based metallic nanogap electrodes is presented, in which the multisegmented Pt/Au/Pt nanowires were electrodeposited in the pores of porous anodic aluminum oxide (AAO) templates first and then thermally annealed to form a nanoscale gap at the interface of Au/Pt. We proposed that the breaking of the multisegmented Pt/Au/Pt nanowires is due to the chemical and physical transformations of the Au segment with O(2). These electrodes are ideally suited for electron-transport studies of chemically synthesized nanostructures, and their utility is demonstrated here by measuring the electronic conduction of short (54-base-pairs) double-stranded (ds) DNA molecules in a dry state.
