Abstract
A method for fabricating metallic micro-nanostructures, the method including: 1) heating a metal and a micro-nanostructure mold to a temperature T, where the metal is a pure metal or an alloy thereof selected from indium (In), germanium (Ge), tin (Sn), bismuth (Bi), lead (Pb), zinc (Zn), aluminum (Al), copper (Cu), gold (Au), silver (Ag), platinum (Pt) and palladium (Pd), T is greater than or equal to 0.5 Tm and less than Tm, with T representing an absolute temperature and Tm representing a melting point temperature of the metal at absolute temperature scale; 2) applying load to press the metal at the temperature T into the mold to obtain a composite structure comprising the mold and the metal; and 3) removing the mold, to obtain the metal with replicated micro-nanostructures.
