摘要

In a previous paper lsqb;D. Schechter, J. Appl. Phys.61, 591 (1987)rsqb; the Leendash;McGill model for computing the populations and carrier concentrations in heavily dopednhyphen;type silicon was systematically explored. In this addendum, the carrier concentration calculated using the Leendash;McGill model is calculated as the doping density is decreased, and is compared with that calculated using the usual dilute doping model. In particular, the extent to which the predictions of the two models agree is explored. It is found that at room temperature the two models agree very closely for doping concentrations below 1times;1017cmminus;3, but at reduced temperatures the coincidence is not so close.
