(a, b) Line patterns of Au/Ag obtained using a sectioned multilayer mask with 680 nm period for 30 min and 90 min exposure, respectively. (c) Lines of Au/Ag NPs fabricated by exposing an Au/Ag film grown on a stepped sapphire to X-rays for 30 min without using a mask. The metal particles aggregated to the step edges to form a line pattern. |
