Abstract

A novel electrically driven molecular rotor device has been designed and fabricated. NDR behaviors were observed owing to the rotation motion on the Cu axel. This is the first time that a rotation induced NDR effect on a solid support was observed. The rotation of the molecules was also confirmed using the optical absorption spectroscopy. From temperature dependence measurements, the activation energy of the rotation was estimated to be 0.3 eV based on the Arrhenius plot.
