Anomalous spin-resolved point-contact transmission of holes due to cubic Rashba spin-orbit coupling.
Evidence is presented for the finite wave vector crossing of the two lowest one-dimensional spin-split subbands in quantum point contacts fabricated from two-dimensional hole gases with strong spin-orbit interaction. This phenomenon offers an elegant explanation for the anomalous sign of the spin polarization filtered by a point contact, as observed in magnetic focusing experiments. Anticrossin...
متن کاملNew perspectives for Rashba spin-orbit coupling.
In 1984, Bychkov and Rashba introduced a simple form of spin-orbit coupling to explain the peculiarities of electron spin resonance in two-dimensional semiconductors. Over the past 30 years, Rashba spin-orbit coupling has inspired a vast number of predictions, discoveries and innovative concepts far beyond semiconductors. The past decade has been particularly creative, with the realizations of ...
متن کاملEquilibrium spin current in graphene with Rashba spin-orbit coupling
The existence of a background spin current under thermodynamic equilibrium is an interesting phenomenon in the two-dimensional electron gas with Rashba spin-orbit coupling (RSOC). Here we study the equilibrium spin current (ESC) in graphene with RSOC. For an infinite graphene with uniform RSOC, we found that the ESC is proportional to λ(2) with λ the Rashba strength and mainly comes from the en...
متن کاملSpin transport study in a Rashba spin-orbit coupling system
One of the most important topics in spintronics is spin transport. In this work, spin transport properties of two-dimensional electron gas in Al(x)Ga(1-x)N/GaN heterostructure were studied by helicity-dependent photocurrent measurements at room temperature. Spin-related photocurrent was detected under normal incidence of a circularly polarized laser with a Gaussian distribution. On one hand, sp...
متن کاملGeneric helical edge states due to Rashba spin-orbit coupling in a topological insulator
We study the helical edge states of a two-dimensional topological insulator without axial spin symmetry due to the Rashba spin-orbit interaction. Lack of axial spin symmetry can lead to so-called generic helical edge states, which have energy-dependent spin orientation. This opens the possibility of inelastic backscattering and thereby nonquantized transport. Here we find analytically the new d...
