Abstract: Molecular electronics is an emerging field that seeks to use individual molecules as electronic components, with the goal of creating devices that are smaller, more efficient, and more versatile than current technologies. In order to explain the mechanism of electron transfer through said molecule, a wide verity of electron transfer formalisms was suggested and used. Yet, some phenomena – such as negative differential resistance (NDR) and hysteresis, observed in recent experiments by the Venkataraman group in Columbia are hard to explain using widely used electron transfer formalisms.
In my talk, I will explain the approaches used in the inquiry of the unique phenomena observed in Venkataraman’s experiments – showing both Hysteretic behaviour and NDR. A novel idea which includes the effect of the external bias on the solution containing the molecule will be presented in order to explain said experiment.
