AbstractWe have deposited carbon films from mixtures of methane and N2 using Plasma Enhanced Chemical Vapor Deposition. By changing the percentage of N2 in the feed gas, we were able to produce films that have various aspect ratios and sp2/sp3 contents. The film with the highest field emission contains spears of aspect ratio of 10:1. We also found that in our sp3-rich films, higher sp2 content enhanced field emission. This is ascribed to improved charge transport to the field emission sites.

ABSTRACTLaser-generated silicon microcone arrays were used as templates for the growth of nanocolumns using laser irradiation as well. The formation mechanism of the microstructure is briefly reviewed, and the origin and growth of nanocolumns are discussed. The formation mechanism of nanocolumns requires highly localized melting, which explains why they fail to form on a flat surface but can grow atop the microcones. Field emission properties from both microcolumns and nanocolumns have been measured. The high aspect ratio (height/tip radius) of nanocolumns makes them suitable for various field emission applications.
