摘要：
Optical Pump Terahertz Probe (OPTP) spectroscopy is a well-established measurement technique with which charge-carrier dynamics of semiconductor nanowires (NW) can be extracted in a noncontact manner. Here in this work, we employ OPTP spectroscopy for measuring temperature-dependent photoconductivity spectra of 3D Dirac Cd3As2 semi-metal nanowires, revealing a high Extrinsic carrier concentration of similar to 2.0 x 10(17) cm(-3) and ultrahigh carrier mobility of up to similar to 13 x 10(3) cm(2)V(-1)s(-1) at a temperature of 5 K.
