摘要：

Dependence of the photoacoustic (PA) signals on the modulation frequency was measured for CdInGaS4 crystals in the reflection and transmission detection configurations (RDC and TDC). The PA signals originate from both the thermal diffusion and photo-excited carrier diffusion processes under TDC. The two processes can be separated by changing the modulation frequency of the excited light. The experimental results show the possibility of characterizing the thermal and electronic properties of CdInCaS4 crystals by the PA technique in TDC.
