Abstract-Dynamic Terahertz Response in the Dirac Semimetal Cd3As2 Induced by Ultrafast Optical Excitation

Wei Lu, Jiwei Ling, Faxian Xiu, Dong Sun,

Hot electron relaxation and coupling in Cd3As2 is studied by employing ultrafast time-domain THz spectroscopy. The excited carriers enhance the absorption of THz and relax in ps-time scales, the cooling rules consistent with mid-IR spectroscopy.
