Publikováno v: Physical Review Letters. 129

Using a spatially-resolved optical pump-probe experiment, we measure the lateral transport of spin/valley polarized electrons over very long distances (tens of micrometers) in a single WSe2 monolayer. By locally pumping the Fermi sea of 2D electrons

Excitonic Linewidth Approaching the Homogeneous Limit in MoS_{2}-Based van der Waals Heterostructures

Autor: F. Cadiz, E. Courtade, C. Robert, G. Wang, Y. Shen, H. Cai, T. Taniguchi, K. Watanabe, H. Carrere, D. Lagarde, M. Manca, T. Amand, P. Renucci, S. Tongay, X. Marie, B. Urbaszek

Publikováno v: Physical Review X, Vol 7, Iss 2, p 021026 (2017)

The strong light-matter interaction and the valley selective optical selection rules make monolayer (ML) MoS_{2} an exciting 2D material for fundamental physics and optoelectronics applications. But, so far, optical transition linewidths even at low
