Controlled ambipolar charge transport through a self-assembled gold nanoparticle monolayer.

An active mechanism for controlling ambipolar charge transport is developed based on self-assembled monolayers of gold nanoparticles. Electron and hole currents are manipulated by controlling the gate bias in order to overcome the intrinsic material limitations. The endurance and retention measurements confirm that this method exhibits good electrical reliability and stability. This solution process approach has potential for applications in large-area printed electronic devices.
