Research Abstract

Electrically-stimulated switching of a molecular monolayer self-assembled on an electrode was electrically detected for the first time, giving us useful information towards the future molecular-scale electric switches. Such self-assembled monolayers inserted into electrode-molecule interfaces in organic transistors were found to effectively cut the electrode-molecule interaction, which revealed anomalous electrical characteristics of the interfaces. Furthermore, detailed conditions were investigated to achieve conducting interfaces between two organic insulator single crystals.
