Generation of Open Circuit Voltage in LB Ultra Thin Films

Langmuir-Blodgett(LB) films of arachic acid and TCNQ(tetracyanoquinodimethane) were prepared in the sample of Al/LB film/Al type where Al are electrodes, and polarization in LB film and dipolar moment of molecules in the films were measured by themally stimulated current(TSC). It is ascertaind in our experiments that dipolar mament of $C_{12}$TCNQ molecule was about 13-15 debye and the moment was directed from the alkyle chain toward TCNQ. Generation of the open circuit voltage was investigated on the z-type and Hetero structure of LB films.
