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 va cuum system were investigated. The films were characterized by transmi ssion electron microscopy (TEM) and electronic spectroscopy. The spect roscopic results evidenced the formation of the charge-transfer comple x system in C-60-TCNQ thin films and the TEM results revealed the micr ostructure of the films. The film thickness is of about 100 nm. The el ectromotive intensity at the transition point is a few 10(7) V/m. The possible mechanism of the electrical phenomena of the films is discuss ed in the paper.
