a Schematic of the fabrication of patterned Au pads on top of the Cu(Cys)2 thin film by photolithography. b Optical (top panels; scale bars represent 200 μm length) and FESEM (bottom panels; scale bars represent 100 μm length) images of the 50, 100, 150, and 200 μm channels (left to right) with Au contact pads on the top of Cu(Cys)2 thin film. Scale bars are provided. c Optical (top panels; scale bars represent 200 μm length) and FESEM (bottom panels; scale bars represent 100 μm length) images of the 50 × 50 μm2, 100 × 100 μm2, 150 × 150 μm2 and 200 × 200 μm2 (left to right) Au contact pads. d Plot of resistance values versus and channel length at 300 K (blue spheres) and 333 K (pink spheres). e Plot of resistance values versus and contact pad area at 300 K (blue spheres) and 333 K (pink spheres). Source data are provided as a Source Data file.
