Abstract :
Field emission features and FIM/FEM images from vacuum arc-prepared carbon films on shape-controlled W tip apexes have been examined, where tens of samples with different film thicknesses and different radii were prepared. The obtained results imply that superior field emission is not due to the protrusions with high aspect ratio but its intrinsic nano-structures.
