Abstract

First-principles electron field emission calculations have been performed on flat and stepped Pt and Pd surfaces. An increase in electron transmission is seen for well-defined stepped surfaces. This stems from the reduction in the work function caused by Smoluchowski electron-smoothing and an increased tunneling contribution from surface parallel wave vectors at the stepped surface. A reduced effective potential at the step site may also contribute to increased electron transmission.
