Abstract

Based on contactless photoconductance measurements of silicon wafers, we have determined the sum of the electron and hole mobilities as a function of doping, excess carrier concentration, and temperature. By separately analyzing those three functional dependences, we then develop a simple mathematical expression to describe the mobility sum as a function of carrier injection wafer doping and temperature from 150 to 450 K. This new parameterization also provides experimental validation to Klaassen's and Dorkel-Leturcq's mobility models in a range of temperatures.
