Title: Using horizontal carbon nanotubes in field emission cathodes
Abstract: Low-threshold field emission is the intrinsic property for nanocarbon materials. Emission characteristics of planar field cathodes with carbon nanotubes (CNT) deposited from solution to Si, Al, Pd substrates were studied. The field emission threshold value for horizontally aligned CNT was found as low as 4 V/μm. However, the field enhancement in these samples is negligible (<;10). We propose to use low threshold field emission CNT films where main field enhancement is achieved by silicon-based technology. A novel design of field emission cathode consisting of horizontally aligned CNT as a part of field enhancing Si structures is shown.
