1/8/2023 0 Comments Tera term 4.83The decay time of the real part of the THz photoconductivity in layered MoS 2 crystal is independent with the pump power, while the imaginary part increases with the pump power. We have analyzed the ultrafast changes of the THz complex photoconductivity deduced from the peak and zero-crossing of THz waveforms. Herein, we investigate the photo-generated carrier dynamics in layered MoS 2 crystal using a time-resolved terahertz (THz) spectroscopy. Ultrafast carrier dynamics, including the carrier photoexcitation and relaxation processes, plays an essential role in improving the performance of molybdenum disulfide (MoS 2)-based optoelectronic devices. 2School of Electronic Engineering, Xi’an University of Posts and Telecommunications, Xi’an, China.1Shaanxi Joint Lab of Graphene, State Key Laboratory of Photon-Technology in Western China Energy, International Collaborative Center on Photoelectric Technology and Nano Functional Materials, School of Physics, Institute of Photonics and Photon-Technology, Northwest University, Xi’an, China.
