摘要：

We report a systematic study of ternary ZnCdTe crystals as terahertz wave emitters and sensors with a femtosecond Ti:sapphire laser. Experimental measurements of the generation and detection of terahertz waves from <110>-oriented Zn1-xCdxTe crystals indicate the optimum composition x=0.05. We also report generation and detection of terahertz wave from doped crystals. For terahertz wave applications, the resistivity of these crystals should be greater than 100 Omega cm.
