Abstract

The idea of utilizing individual molecules as the electronic device components has generated tremendous attention in understanding the basic charge transport characteristics and potential technological applications of molecular electronic junctions. But, fabrication of stable and reliable molecular junctions has been a long-standing challenge in molecular electronics. In this talk, I will review our group’s research effort towards fabrication and characterization of high-yield molecular electronic junctions with device functionalities. Specifically, I will present a series of our experimental advancements to achieve high yield and reliable molecular junctions, such as employing conducting polymer or graphene film as an intermediate electrode layer, or spin-coated reduced graphene oxide layer and directly transferred metals as a top electrode in molecule electronic devices. And then, when time allows, I will give a brief overview of our research work on related topics: polymer or perovskite-materials and 2D materials with molecular treatment.
