Abstract: A system for characterizing a semiconductor sample is disclosed. The system comprises a measurement subsystem, a data analysis subsystem, and a statistical analysis subsystem coupled to each other via an interconnection. The measurement subsystem excites a semiconductor sample by shining light on one or more points in the semiconductor sample to generate electron hole pairs, which creates a change in conductivity of the semiconductor sample. The measurement subsystem measures one or more voltage decay curves corresponding to the one or more points in the semiconductor sample based on the changes in conductivity, and transmits the measured voltage decay curves to the data analysis subsystem. The data analysis subsystem extracts one or more normalized decay curves from the transmitted measured voltage decay curves, which the data analysis subsystem then transmits to the statistical analysis subsystem. The statistical analysis subsystem analyzes the transmitted normalized decay curves.
