Mesoscopic valley filter in graphene Corbino disk containing a p–n junction
The Corbino geometry allows one to investigate the propagation of electric current along a p-n interface in ballistic graphene in the absence of edge states appearing for the familiar Hall-bar
Perfect valley filter based on a topological phase in a disordered Sb monolayer heterostructure
The hydrogenated $\mathrm{Sb}$ monolayer epitaxially grown on a ${\mathrm{LaFeO}}_{3}$ substrate is a novel type of two-dimensional material hosting quantum spin-quantum anomalous Hall (QS-QAH)
Valley current and spin-valley filter in topological domain wall
The gapless edge states with a certain spin and valley index can be realized in topological domain walls. In this work, we study various domain walls thoroughly and demonstrate that multiple kinds of
Topological valley transport at the curved boundary of a folded bilayer graphene
The development of valleytronics demands long-range electronic transport with preserved valley index, a degree of freedom similar to electron spin. A promising structure for this end is a topological
Manipulation and Characterization of the Valley-Polarized Topological Kink States in Graphene-Based Interferometers.
TLDR
The proposed Aharanov-Bohm interferometer provides an experimentally feasible route to manipulate and characterize the valley-polarized topological kink states in classical wave and electronic graphene-type crystalline systems.
Valley-Polarized Quantum Anomalous Hall Effect in Ferrimagnetic Honeycomb Lattices.
TLDR
This work proposes a different mechanism of VP-QAHE by introducing an intrinsic staggered magnetic exchange field and develops a general picture of valley dependent band inversion in honeycomb lattice using a low energy k·p model.
Valley-selective topologically ordered states in irradiated bilayer graphene
Gapless bilayer graphene is susceptible to a variety of spontaneously gapped states. As predicted by theory and observed by experiment, the ground state is however topologically trivial, because a
Pure spin current and perfect valley filter by designed separation of the chiral states in two-dimensional honeycomb lattices
We propose a realization of pure spin currents and perfect valley filters based on a quantum anomalous Hall insulator, around which edge states with up spin and down spin circulate. By applying
Dispersionless wave packets in Dirac materials
Abstract We show that a wide class of quantum systems with translational invariance can host dispersionless, soliton-like, wave packets. We focus on the setting where the effective, two-dimensional
