Abstract
Polycrystalline diamond films have been annealed under O-2 at 600 degr ees C, or have been dipped in a H2SO4/CrO3 solution. Both treatments r esult in the formation of a thin electrically insulating layer at the top of the films. Subsequent metallization results in the formation of a metal/insulated diamond tunnel diode with a potential barrier for h oles of 0.85 eV, and with a Fermi level localized at about 0.45 eV abo ve the diamond valence band.
