Abstract
A contactless method to determine the carrier mobility sum in silicon wafers, based on a comparison between photoluminescence and photoconductance measurements is presented. The method is applied to monocrystalline silicon wafers and the results are found to be in good agreement with well-established mobility models and another measurement method. The potential of the proposed method to determine the carrier mobility sum of multicrystalline and compensated silicon wafers is then demonstrated.
