Breakdown fields in the 106÷107 V/cm range have been reported in several papers for natural diamonds (Bogdanov et al. ; Konorova et al. ). Breakdown fields in excess of 2·107 V/cm have been reported by (Landstrass et al. ) for homoepitaxial diamond films.
|Ionization rates for electrons and holes (αi=β i) versus 1/F.
