  • Abstract
    Funneling is qualitatively discussed in detail, and a quantitative analysis is given for the total (time-integrated) collected charge. It is shown that, for an n+/p junction, the total collected charge QT is given by QT=(1+μn/μp) QD+2Qdiff, where QD is the charge initially liberated in the depletion region and Qdiff is charge collected by diffusion. This equation does not apply to very short ion tracks or to devices having a thin epilayer. A numerical example is presented, and a comparison is made with PISCES results
