Description: 
Conductance switching associated with the photoisomerization of azobenzene-based (Azo) molecules was observed in nanoscopic metal−molecule−metal junctions. The junctions were formed by using a conducting atomic force microscope (C-AFM) approach, where a metallic AFM tip was used to electrically contact a gold-supported Azo self-assembled monolayer. The measured 30-fold increase in conductance is consistent with the expected decrease in tunneling barrier length resulting from the conformational change of the Azo molecule.
