Abstract

A fully feasible and versatile way to fabricate highly reliable organic-transistor memory devices is made possible by a novel design of the charge-trappling layer. Gold@silica (core-shell)-structured nanoparticles are synthesized and used as the charge-trapping layer. Superior electrical reliability is obtained because the silica shell acts as a built-in tunnel potential barrier.
