Description
Summary:This paper reports on study of blade-shaped field emission nanostructures based on multigraphene films on silicon carbide. We carry out numerical simulations of the distribution of the electric field in a nanoscale interelectrode gap of a planar field emission cell. The simulation parameters are based on the dimensions of the experimental sample of a planar emission cell with a blade-shaped emitter. Design of the field emission cell aimed at minimizing the local field amplification at the emitter corners have been proposed. The initial difference in the electric field strength at the corners of the emitter and in the center was 2.5 times. The proposed design allows to obtain the electric field strength at the corners corresponding to the values in the center of the emitter.
