摘要： A method for the replication of a textured surface of a master is disclosed, in which the textured surface of the master is comprised of micron-scale cones having nano- or micro-scale surface features. Alternatively, the master may be comprised of micron-scale structures, nano-scale structures, and micron scale structures having nano-scale surface features. Replication can be achieved through a molding or embossing technique. Using these technique, the textured surface of the master is faithfully replicated onto the surface of the replica. A number of representative materials and additional processing steps are also disclosed. The replicated texture exhibits many useful properties, including enhanced hydrophobicity and reduced light reflection properties, making the disclosed method a simple and attractive alternative to existing texturing techniques.

摘要： The surface of a material is textured and by exposing the surface to pulses from an ultrafast laser. The laser treatment causes pillars to form on the treated surface. These pillars provide for greater light absorption. Texturing and crystallization can be carried out as a single step process. The crystallization of the material provides for higher electric conductivity and changes in optical and electronic properties of the material. The method may be performed in vacuum or a gaseous environment. The gaseous environment may aid in texturing and/or modifying physical and chemical properties of the surfaces. This method may be used on various material surfaces, such as semiconductors, metals and their alloys, ceramics, polymers, glasses, composites, as well as crystalline, nanocrystalline, polycrystalline, microcrystalline, and amorphous phases.
