ㅇ 요약 : 

There is an increased interest in understanding electron transfer across single molecule junctions and metal/organic interfaces as this has implications in the field of organic electronics and photovoltaics. In this presentation, I will show how to measure directly the electronic energy level alignment in single molecular junctions by using a scanning tunneling microscope-based break-junction technique. Furthermore, instead of using precious metals such as Au, Ag and Pd, I will introduce a hybrid device structure with the molecule trapped across a gold/graphite gap. These junctions rectify and have among the highest rectification ratios reported for a molecular junction. This work introduces the electrode as a tunable variable for realizing nonlinear device phenomena in hybrid junctions formed with layered two-dimensional materials.
