7 p, 2.8 MB Proximity-induced spin-orbit coupling in graphene/ Bi1.5Sb0.5Te1.7Se1.3 heterostructures / Jafarpisheh, S. (Peter Grünberg Institute) ; Cummings, Aron (Institut Català de Nanociència i Nanotecnologia) ; Watanabe, Kenji (National Institute for Material Science (Tsukuba, Japan)) ; Taniguchi, Takashi (National Institute for Material Science (Tsukuba, Japan)) ; Beschoten, Bernd (RWTH Aachen University) ; Stampfer, Cristoph (RWTH Aachen University)
The weak intrinsic spin-orbit coupling in graphene can be greatly enhanced by proximity coupling. Here, we report on the proximity-induced spin-orbit coupling in graphene transferred by hexagonal boron nitride (hBN) onto the topological insulator Bi1. [...]

We present time-resolved Kerr rotation measurements, showing spin lifetimes of over 100 ns at room temperature in monolayer MoSe. These long lifetimes are accompanied by an intriguing temperature-dependence of the Kerr amplitude, which increases with temperature up to 50 K and then abruptly switches sign. [...]
