CHARGE TRANSFER IN THE PRESENCE OF POTENTIAL BARRIERS

Numerical and analytical solutions of the carrier continuity equation are found for the problem of charge transfer in charge‐coupled devices in the presence of potential barriers. The analytical solution is for a rectangular potential barrier and is useful for obtaining a qualitative understanding of charge transfer over a potential barrier. Numerical results show that the charge transfer inefficiency is strongly affected when the shape of the potential barrier is varied and the height of the potential barrier remains fixed.
