Traditional g-C 3 N 4 generally shows a layered … WebThe photocarrier generation in STO layers and the substrate can be ignored due to its transparency to the pump laser beam. A photoelastic modulator (HINDS instrument, 100 kHz) was used to modulate the pump beam, and the probe beam monitored the pump-induced changes in reflectivity with a time delay of up to 300 ps.
