Abstract:
A method for making a nano-stamp comprising the steps of:sputtering a first layer of one type of material on a substrate; sputtering a second layer of a second material on top of the first layer; repeating the two previous steps until a superlattice structure having a desired number of alternate layers of different material has been formed; cutting through the superlattice structure transverse to the layers; atomically polishing the cut surface of the superlattice; and applying an etchant material to etch away the softer one of the alternate layers of material in the superlattice to a sufficient depth thereby to form a nano-stamp comprising a grid of very thin line edges separated by very thin spacings on the order of 25 nanometers or less and as low as 1 nanometer.
