We demonstrate systematic work function tuning of thiol-based SAM-modified gold electrodes with high controllability and sensitivity as high as 0.05 eV using vacuum ultraviolet technique (VUV). Under different irradiation times, both work function and wettability of the metal surface is modified. Fine tuning of the electrode work function is demonstrated by observable changes in the reverse current of a polymer Schottky diode. Additionally, the change in SAM chemical functionality validates the work function changes of VUV-irradiated electrodes. Our selective work function patterning on a single Au electrode via VUV could also reduce the required fabrication steps for more complex circuits.
