cf4 Equipment for middle voltages

We describe an ultra-small structure and a method of producing the same. The structures produce visible light of varying frequency, from a single metallic layer. In one example, a row of metallic posts are etched or plated on a substrate according to a particular geometry. When a charged particle beam passed close by the row of
