Ionized cluster beam deposition of C-60, Ag-TCNQ thin films and electrical switching phenomena

The ionized cluster beam deposition of Ag-tetracyanoquinodimethane (TCNQ) and C-60-TCNQ thin films is reported. These thin films were characterized by transmission electron microscopy and electron absorption spectroscopy. The microstructure of the thin films and the formation of a C-60-TCNQ thin film were observed. Furthermore, the electrical properties of the thin films were measured and both films were able to exhibit electrical bistability. The conduction mechanism of the polymer thin films with Ag and C-60 is discussed.
