Abstract: A simple, cost-effective, compact and efficient photothermal diffusion wave analyzer for 1 Hz-150 kHz frequency band has been developed and analyzed. The sensitivity is 12 nV and the total error is about 1.5% at 60 dB dynamic reserve, excluding the laser intensity variation that may be corrected. The input voltage and current noises are 15nV/ and 2fA/, respectively. The low power consumption of about 4 W is advantageous for long time off-line applications. The instrument has been used for the metrology of silicon wafers by radiometric simulations. Results regarding the studies on transport parameters and contamination control are presented.
