Abstract:
1. A method of imprinting microfeatures or nanofeatures into an amorphous metal alloy layer, the method comprising the steps of: a) heating an amorphous metal alloy layer to a temperature within a supercooled liquid region of the amorphous metal alloy to soften the amorphous metal alloy layer; b) transferring a pattern into the softened amorphous metal alloy layer by: c) cooling the amorphous metal alloy to a temperature below the supercooled liquid temperature region of the amorphous metal alloy to resolidify the amorphous metal alloy layer, wherein the amorphous metal alloy layer is disposed on a substrate, said substrate comprising a material selected from the group consisting of silicon, quartz, alumina and nickel-tungsten.
