| Research Abstract |
We have investigated the basic phenomena in organic ultra-thin films using inelastic electron tunneling spectroscopy (IETS). The results provide valuable information for highdensity recording system.
[1] IETS in diacetylene monomer films
1) IETS corresponding to the molecular adsorption and polymerization is observed.
2) Chenge of IETS patterns can be controlled by the voltage pulses.
[2] IETS in TCNQ/TMPD adsorption LB films
3) IETS corresponding to the charge transfer between TCNQ and TMPD is obtained.
4) A marked change of IETS by voltage pulses is observed.
5) A reversible change of IETS is also observed.
The basic experimental results show the potential of a new high-density recording system using IETS and STM tip.
