Micro-amplitude vibration-assisted scratching: a new method for one step and controllable fabrication of the microscale V-groove and nanoscale ripples

Highlights A micro-amplitude vibration-assisted scratching method was proposed. One step and controllable fabrication of microscale V-groove and nanoscale ripples was achieved. The effects of processing parameters on the resultant structures were explored. Relationships between processing parameters and dimensions of the resultant structures were established. Complex patterns were fabricated on flat and curved surfaces, achieving various structural colors.
