Atomistic study on dithiolated oligo-phenylenevinylene gated device

Thanks to their semiconducting behavior, conjugated molecules are considered as an attractive candidate for future electronic devices. Understanding the charge transport characteristics through such molecules for different device applications would accelerate the progress in the field of molecular electronics. In addition, it would become more feasible to introduce/enhance specific properties of molecular devices. This theoretical paper focuses on atomistic simulation and characterization of novel molecular FET employing dithiolated oligo-phenylenevinylene molecules. The simulation is validated by its agreement with the experimental measurements conducted on the same molecules. The employed molecule has oxygen linkers, which are responsible for the strongly nonlinear current characteristics on the molecular device. We perform a thorough atomistic device analysis to illustrate the principles behind the nonlinear current characteristics and the gating effect.     «
