Abstract:

Electron transport through organic molecular layers is an essential issue in molecular electronics. The electrical testing by employing gallium-indium alloy(EGaIn) electrodes is well recognized because of its high junction formation rate, reliability, and user-friendly operation. It thus has been extensively adopted in analyzing the charge transport through self-assembled monolayers(SAMs). This review outlines the principle and experimental operation of the EGaIn technique, introduces the recent progress in molecular electronics using the EGaIn technique, and finally gives a prospect.

Key words: Gallium-indium alloy, Self-assembled monolayer, Charge transport, Molecular electronics
