Description:
Author(s): C. R. Zhu, K. Zhang, M. Glazov, B. Urbaszek, T. Amand, Z. W. Ji, B. L. Liu, and X. Marie We have experimentally studied the pump-probe Kerr rotation dynamics in WSe2 monolayers. This yields a direct measurement of the exciton valley depolarization time τv. At T=4K, we find τv≈6 ps, a fast relaxation time resulting from the strong electron-hole Coulomb exchange interaction in bright exci... [Phys. Rev. B 90, 161302] Published Mon Oct 06, 2014
