Abstract

Organic ultra thin films about 500${\AA}$ in thickness are fabricated by LB(Langmuir-Blodgett) technique and their gas detect properties are investigated. The LB films deposited are made of the specimen named as N-docosyl pyridinium(TCNQ) and the deposition is verified by capacitance conductivity measurement. From the study of gas detect properties with I-V characteristics and UV spectrum we have found that their conductivities were increased about 3 times of magnitude and peaks of UV spectrum were decreased.
