High-yield fabrication of molecular vertical junctions.

ABSTRACT

High-yield fabrication and characterization of a ferrocene-based molecular device is reported. This device, fabricated with the use of modified nanocavity architecture shows very high yield, thus providing a template for exploring the transport properties of molecular junctions. The ferrocene-based devices show multiple negative differential peaks with high reproducibility and temperature stability. We use the multiple arrays to investigate the top-contact effect on the NDR signal at different locations in the wafer.
