Author(s): Y. M. Dai, J. Bowlan, H. Li, H. Miao, S. F. Wu, W. D. Kong, Y. G. Shi, S. A. Trugman, J.-X. Zhu, H. Ding, A. J. Taylor, D. A. Yarotski, and R. P. Prasankumar WTe 2 has recently been reported to exhibit extremely large magnetoresistance, which may find potential applications in devices such as highly sensitive magnetic sensors and hard drives. In this paper, using ultrafast optical spectroscopy, the authors track the relaxation of photoexcited carriers in the time domain as they return to equilibrium in WTe 2 . Their experimental results not only resolve the time scales that ultimately limit potential applications of this material in electronic devices, e.g., high-speed hard drives, but also shed new light on the mechanisms governing the extremely large magnetoresistance.
