Abstract

In a structure comprising an ultra-sharp silicon tip coated with a layer of material, the silicon is removed from the structure. The remaining material is utilized as a mold. Metal deposited in the mold replicates the original silicone tip. In this way, ultra-sharp all-metal tips suitable, for example, as field-emitter sources are provided.
