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...http://www.google.com.hk/patents/US7758739?utm_source=gb-gplus-share專利 US7758739 - Methods of producing structures for electron beam induced resonance using plating and/or etching
