"Chemical Equation Presented" Flicking the switch: Photoirradiation has a dramatic effect on the superconducting properties of a passivated ultrathln Nb film functlonallzed with a photochromic self-assembled azobenzene (AZ) monolayer (see picture). These effects can be attributed to photoisomerization-induced changes in the amount of charge transfer between the substrate and the photochromic monolayer. The changes are accompanied by alternation of the surface dipoles.
