Probing the Orbital Levels of Engineered Fullerenic Molecules from a Nonvolatile Memory Cell

Abstract

The Coulomb blockade behavior was observed for both C 60 -PCBM and C 70 -PCBM at room temperature utilizing a nonvolatile memory cell fabricated through a liquid-transfer process. Room-temperature and low-temperature (10K) electrical characterizations verified the blockade effect was originated from both molecular energy levels and single electron charging energy. Molecular orbital energy was extracted and shown good agreement with the literature [1].The successful integration and operation of this hybrid structure signified a strong potential for molecule-based electronic device design.
