Development of Metal Nano-painting Method Using Visco-plasticity Induced by an Oscillated Nano-contact

Atomic force microscopy (AFM)-based nanopainting is proposed for a method of metallic patterning. The Au film coated on a cantilever tip is painted as Au nanodots (NDs) onto a sapphire substrate through an effective utilization of Au viscoplastic flow induced by the ultrasonic resonance of a concentrated-mass cantilever in a second vibration mode. The present method makes it available to paint in individual Au ND at intended location to avoid introducing the unnecessary damage into the entire substrate. Moreover, it is independent of the conductivity of the substrate and operation environment.
