Abstract

Differences between ethylene-glycol and alkyl chains are examined. Their charge transport properties and their molecular orbital energies were investigated using DFT computations. The orbitals show some overlap between oxygen p-orbitals, supporting the superexchange theory as explanation for higher charge transport in EG compared to alkyl. The charge transport calculation revealed a lack of interaction between EG and the gold electrodes, inhibiting charge transport compared to the alkyl which had a terminal thiol. However, a large peak in the transmission spectrum of EG aligns with the oxygen p-orbitals, providing more support for the superexchange theory.
