Cold Cathodes for Applications in Poor Vacuum and Low Pressure Gas Environments: Carbon Nanotubes Versus Zinc Oxide Nanoneedles
(2008-09-09)
Effects of gas pressure on the electron field emission (FE) properties of zinc oxide (ZnO) nanoneedles and carbon nanotubes (CNTs) were investigated. The FE properties for ZnO nanoneedles almost fully recovered after being ...
