MICROWAVE PHOTOCONDUCTANCE SPECTROMETER AND METHODS OF USING THE SAME

摘要

The present disclosure relates to a steady-state microwave conductivity method that includes modulating a light beam to form an amplitude modulated light having a modulation frequency 1, producing a microwave waveform, exposing a sample to the amplitude modulated light and a first portion of the microwave waveform to produce an amplitude modulation signal on the first portion of the microwave waveform, and mixing a second portion of the microwave waveform and the amplitude modulation signal to produce a first signal and a second signal.
