Modulation of charge conduction in ZnO nanowires through selective surface molecular functionalization

Two-terminal devices were fabricated using unintentionally doped Zinc Oxide (ZnO) nanowires (NW) grown via a chemical vapor deposition technique to study the influence of surface functionalization on their transport properties. Organic molecules with differing functional groups demonstrated contrasting effects on the charge transport of the nanowires depending on the polarity and orientation of the molecules.
