Writing charges into single molecules embedded in thin polymer films by Atomic Force Microscopy

C. Chotsuwan and S. C. Blackstock

  • Single molecule charging (electrochemistry) is accomplished in diluted polymer matrixes: this results provides a way to control electron placement on the nanometer scale, an important capability for the development of molecular electronic technologies, including information storage in molecules, the application in this case.
  • An AFM tip charging radius of 1.9 nm has been determined from these experiments: the charged molecule can be used to measure the resolution of the AFM charge injection process, an important technological parameter for the use of AFM-based charge patterning in other media.
