Gate-Controlled Spin-Valley Locking of Resident Carriers in WSe_{2} Monolayers.
Using time-resolved Kerr rotation, we measure the spin-valley dynamics of resident electrons and holes in single charge-tunable monolayers of the archetypal transition-metal dichalcogenide (TMD) semiconductor WSe_{2}. In the n-type regime, we observe long (∼130 ns) polarization relaxation of electrons that is sensitive to in-plane magnetic fields B_{y}, indicating spin relaxation. In marked co...
متن کاملBound states and magnetic field-induced valley splitting in gate-tunable graphene quantum dots
The magnetic field dependence of energy levels in gapped singleand bilayer graphene quantum dots (QDs) defined by electrostatic gates is studied analytically in terms of the Dirac equation. Due to the absence of sharp edges in these types of QDs, the valley degree of freedom is a good quantum number. We show that its degeneracy is efficiently and controllably broken by a magnetic field applied ...

متن کاملWhat Gate? Gate what?
Since economic liberalization period, Chinese housing typologies have experienced a dramatical change. From the traditional Siheyuan building type to the current gated communities, which prototype has become the most widespread residential housing type in modern China Cities. At the same time, many negative feedbacks about the city life have been appearing, such as traffic congestion, the loss ...
متن کاملUpending the Uncanny Valley
Although robotics researchers commonly contend that robots should not look too humanlike, many artforms have successfully depicted people and have come to be accepted as great and important works, with examples such as Rodin’s Thinker, Mary Cassat’s infants, and Disney’s Abe Lincoln simulacrum. Extending this tradition to intelligent robotics, the authors have depicted late sci-fi writer Philip...
