摘要

The electric field around a nanowall that is vertically mounted on a planar cathode is studied. The system is designed as a cold field electron emitter or an electron tunneling line scanner. Exact expressions for the electric potential and the edge field enhancement factor are obtained for arbitrary cathode-anode distances. It is found that the finite distance correction is significant for the cathode-anode distances less than twice the height of the nanowall. The angle-dependent transmission probability implies that the forward emission is dominant.
