CHANGE OF INELASTIC ELECTRON-TUNNELING SPECTRA OF ORGANIC ULTRATHIN FILMS BY VOLTAGE PULSES AND APPLICATION TO HIGH-DENSITY RECORDING-SYSTEMS

Electron tunneling spectroscopy is important from both characterizatio n and potential application viewpoints because it provides valuable in formation about the structure, orientation, and interactions of molecu les in organic thin films. In particular, inelastic electron tunneling spectroscopy (IETS) using a scanning electron tunneling microscope re veals spatial and spectral information and is attractive as a high-den sity storage system. We describe the basic experimental results of cha nges in IETS patterns of organic monolayers induced by the voltage pul se, and the potential for application to high-density recording system s.
