Abstract

This paper demonstrates controlled plasmon-induced single-molecule switching of peryleneanhydride on a silicon surface using a plasmon-resonant tip in low-temperature scanning tunnelling microscopy. The switching rate is controlled by tip height with 0.1-Å precision, and plasmon-induced reactivity is modified by molecular chemical substitution. This metal-single-molecule-semiconductor junction offers a controllable platform for nano-optoelectronics.
