Electrical Phenomena of C_(60)-Tetracyanoquinodimethane Thin Films

The electrical properties of C_(60)-tetracyanoquinodimethane(TCNQ)thin films fabricated by using an ionized-cluster-beam method in a high vacuum system were investigated.The films were characterized by transmission electron microscopy(TEM)and electronic spectroscopy.The spectroscopic results evidenced the formation of the charge-transfer complex system in C_(60)-TCNQ thin films and the TEM results revealed the microstructure of the films.The film thickness is of about 100nm.The electromotive intensity at the transition point is a few 107 V/m.The possible mechanism of the electrical phenomena of the films is discussed in the paper.
