| Abstract |
In this paper, we study the electrical conduction mechanism in Langmuir-Blodgett(LB) ultra thin films for which the LB device has a metal/LB films(TCNQ)/metal sandwich structure. Our experiments show that the current at the LB device does not depend on the temperature at below 0 C. This phenomena confirm that the electrical conduction current is a tunnel current inherent to ultra thin films. However, the current depends upon the temperature near the room temperature. This phenomena indicates the electeical conduction current is a Schottky current inherent to ultra thin films. |
