Abstract
High-resolution nanoreliefs, which possess a controllable height change (, up to film thickness) and transmittance or reflectance, have been successfully fabricated in -thick Sn films by using pulsed laser direct writing. Different from current micro/nanofabrication techniques, the height change of the nanoreliefs is generated by a laser-induced-thickening process. The majority of the height change comes from a balling and coarsening effect rather than oxidation of grains. Because both optical density and of the nanoreliefs are almost linear to laser power, the optical images can highly resemble the topographic images. This technique is useful for fabricating complicated nanorelief structures and fine images.
