文摘

The mechanical patterning of thin films has received recent attention due to significant potential for efficient nanostructure fabrication. Forsolid films, mechanically thinning wide areas remains particularly challenging. In this work, we introduce a new plastic ratchet mechanisminvolving small amplitude (<10 nm), oscillatory shear motion of the forging die. This isothermal mechanism significantly extends mass transportacross surfaces, broadening the scope of nanoscale processing for a potentially wide class of solid ductile materials.
