charge transport in molecular transistor incorporating a pair of Mn-phthalocynine molecule

charge transport phenomena of single molecule transistor are of great interests not only to understand quantum transport in confined structure, but also to study molecular properties at individual molecule level. Single molecule transistors have been realized successfully in the past years and findings including Kondo resonance, quantum phase transition among others were discovered. In this talk, we will discuss our new experimentals finding when two molecules were incorporated in a molecular devices. When two Mn phthalocynine molecules are close to each other, they will coupled to each other though electric static field and in some case exchange electrons in between, leading to unique and different physics picture depending on coupling strength. molecular gating and exchange coupling will be adressed.
