    摘要: Systems and methods are described for a single self-aligned carbon nanofiber emitters within a dielectric well. A method, includes: providing a substrate; defining lithographically a catalyst particle, the catalyst particle coupled to the substrate; depositing a dielectric layer, the dielectric layer coupled to the substrate; depositing an extractor layer, the extractor layer coupled to the dielectric layer; forming an extractor aperture in the extractor layer; forming a dielectric well in the dielectric layer to uncover the catalyst particle; and then fabricating at a location of the catalyst particle and within the dielectric well a single self-aligned carbon containing tip i) having a base located substantially at the bottom of the dielectric well and ii) extending substantially away from the substrate using plasma enhanced chemical vapor deposition.
