Effect of the metal/organic interface phenomena on the current-voltage characteristics of organic single electron tunneling device
The current-voltage (I-V) characteristic of Au/PI/(Rh-G2 + PI)/PI/Au (or Al) junctions was examined. An asymmetrical I-V characteristic with several steps was observed for Au/PI/PI:Rh-G2/PI/Al junctions, whereas a symmetric I-V characteristic with steps was obtained for Au/PI/PI:Ph-G2/PI/Au junctions. It was concluded that the presence of metal/organic interfacial states made a significant contribution to the I-V characteristics of these junctions.
