Spin-valley filtering in strained graphene structures with artificially induced carrier mass and spin-orbit coupling.
The interplay of massive electrons with spin-orbit coupling in bulk graphene results in a spin-valley dependent gap. Thus, a barrier with such properties can act as a filter, transmitting only opposite spins from opposite valleys. In this Letter we show that a strain induced pseudomagnetic field in such a barrier will enforce opposite cyclotron trajectories for the filtered valleys, leading to ...

متن کاملStrain-Controlled Valley Splitting in Si-SiGe Heterostructures
A splitting between equivalent valleys larger than the spin splitting was recently reported in a gate confined electron system in thin Si films grown on SiGe substrate [1]. This degeneracy lifting reduces scattering and improves the coherence time. The valley splitting larger than the spin splitting opens a way to build spin qubits, which makes silicon-based quantum devices promising for future...
متن کاملControlled assembly of graphene sheets and nanotubes: Fabrication of suspended multi-element all-carbon vibrational structures
We report on the fabrication and operation of a multi-element vibrational structure consisting of two graphene mechanical resonators coupled by a nanotube beam. The whole structure is suspended. Each graphene resonator is clamped by two metal electrodes. The structure is fabricated using a combination of electron-beam lithography and atomic-force microscopy nano-manipulation. This layout allows...
متن کاملParity and valley degeneracy in multilayer graphene
We study spatial symmetry in general ABA-stacked multilayer graphene to illustrate how electronic spectra at the two valleys are related in a magnetic field. We show that the lattice of multilayers with an even number of layers as well as that of monolayer graphene satisfy spatial inversion symmetry, which rigorously guarantees valley degeneracy in the absence of time-reversal symmetry. A multi...
