Abstract

Molecular devices utilizing active self-assembled monolayer (SAM) (containing nitroamine (2′-amino-4-ethynylphenyl-4′-ethynylphenyl-5′ -nitro-1-benzenethiolate) and nitro (4-ethynylphenyl-4′-ethynylphenyl-2′-nitro-1-benzenethiolate) redox center) as the active component are reported. Current-voltage measurements of the devices exhibited negative differential resistance at room temperature and an on-off peak-to-valley ratio in excess of 1000:1 at low temperature.
