Electron field emission from surfaces with steps

Merrick, Ian, Inglesfield, John Ewan and Attard, Gary Anthony 2005. Electron field emission from surfaces with steps. Physical review. B, Condensed matter and materials physics. 72 (3) , 033403. 10.1103/PhysRevB.72.033403

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.
