Abstract:

Functional molecular electronics based on eutectic galliumindium as top electrode and self-assembled monolayer(SAM) as active layer is one of the research hotspots in recent years. Domestically, the study on EGaIn-based functional molecular junctions(MJ) is still in the beginning state. This review introduces the advantages of EGaIn as top electrode and the fabrication of SAM-MJ in detail, and shows recent workers on rectifiers, memory, opto-electrical switches, thermoelectrics, and solid-state impedance and so on. We analyze the challenges of EGaIn-based molecular junctions and propose the future development directions.

Key words: Eutectic gallium-indium, Self-assembled monolayer, Functional molecular junction, Molecular electronics
