   Minority-carrier parameters from silicon are analysed under heavily doping conditions. An expression for minority-carrier current density is obtained in terms of the reduced fermi energy for electrons (holes). This has been utilised to derive other parameters in a different form suitable for device modelling. the theoretical results are made useful to study the variation of the minority-carrier lifetime and current density with impurity concentration. Some results have been compared with earlier works. Moreover, the temperature dependence of the miority-carrier parameters is studied on the basis of the presented analysis.
