Abstract
Analysis of capacity–voltage dependencies for CdF2 crystals with Schottky barrier testifies to a strong compensation of donors in the depletion layer. It is proposed that this effect is due to formation at the interface of two-electron Cd0 excitations, which are unstable in CdF2 but diffuse into depletion layer due to a finite lifetime caused by a potential barrier preventing their instantaneous decay.
