Abstract:
1. A method for patterning a substrate with a microstructured or nanostructured target material, said method comprising the steps of: providing a layer of said target material on a surface of said substrate; contacting said layer of target material with a photoablation assisting material, wherein said photoablation assisting material at least partially integrates into said layer of target material, thereby generating a layer of target material integrated with said photoablation assisting material; and exposing selected regions of said layer of target material integrated with said photoablation assisting material to electromagnetic radiation in the ultraviolet region of the electromagnetic spectrum having wavelengths and a fluence sufficient to initiate removal of the photoablation assisting material, thereby generating a force which removes a portion of said target material in the layer of target material integrated with said photoablation assisting material, wherein said wavelengths and said fluence of said electromagnetic radiation do not result in direct ablation of said target material; thereby patterning said substrate with said microstructured or nanostructured target material.
