Abstract: The present application is directed to a method of modifying a surface of an article and includes irradiating pulsed laser light output at repetition rates in excess of about 1kHz, directing the laser light to a spot on the surface, and producing micro-grooved surfaces having one or more grooves formed thereon, the grooves having groove depths in the range of about 1 ?m to about 100 ?m.

Abstract: The invention provides a method of depositing a layer of a conductive material, e.g. metal, metal oxide or electroconductive polymer, from a patterned stamp, preferably a soft, elastomeric stamp, to a substrate after an organic layer has been transferred from a patterned stamp to an organic layer over the substrate. The patterned metal or organic layer may be used for example, in a wide range of electronic devices. The present methods are particularly suitable for nanoscale patterning of organic electronic components.
