Electrical Phenomena of C₆₀-Tetracyanoquinodimethane Thin Films

The electrical properties of C₆₀-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 C₆₀-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.
