SEM image of nanotrench made by ion milling. The image was acquired using 45° angle with of gold coating.
Schematic illustration showing the fabrication of SNS nanotrench junction with SAM solution surface treatment.
Resistance vs temperature measurement of YBCO/Au/YBCO junction and TX-YBCO/Au/TX-YBCO junction. YBCO was stored in desiccator for three days and gold was deposited without SAM cleaning (A) and with SAM cleaning (B). TX-YBCO was exposed to the atmosphere for seven days and gold was deposited without SAM cleaning (C) and with SAM cleaning (D).
Relative values for superconductivity for YBCO and TX-YBCO with SAM cleaning and without SAM cleaning.
