Strongly anisotropic spin relaxation observed in graphene when interfaced with transition metal dichalcogenides

Experimentalists of the ICN2 Physics and Engineering of Nanodevices Group, led by ICREA Prof. Sergio O. Valenzuela, have found evidence that the spin-orbit coupling induced in graphene by proximity to transition metal dichalcogenides affects electron spins differently depending on their orientation. Published in Nature Physics, this work suggests new approaches to controlling the transport of spin and valley information in future spintronics devices.

Thermal gradients shown to enhance spin transport in graphene

ICN2 researchers have demonstrated that the application of a thermal gradient in spintronic devices can cause spin signal to increase as a result of a novel thermoelectric phenomenon predicted and subsequently observed in graphene. Specifically, the enhanced spin signal is two orders of magnitude larger than anything previously reported for thermal effects in metals. Published in Nature Nanotechnology, these findings push at the frontier of graphene spintronics technologies.
