Rectifying phenomenon of Cu-TCNQ organometallic crystallite device

This study describes the fabrication sequence of a prototype device based on the assembly of copper-tetracyanoquinodimethane (Cu-TCNQ) crystallites in a specially designed and prepared electrode structure. The assembed Cu-TCNQ organometallic salt was synthesized by using the spontaneous electrolysis growth technique. The results of the electrical measurement on this device have clearly shown a typical rectifying characteristic. It is suggested that this rectifying phenomenon is mainly related with the Cu-TCNQ molecular homojuction formed by in-microregion contact.
