Rashba spin-orbit coupling (SOC) described by odd powers of $\mathbf{k}$ terms in semiconductor quantum wells (QWs) plays a critical role in spintronics and quantum computing. It was believed that the Rashba SOC in two-dimensional hole gases (2DHGs) is a $\mathbf{k}$-cubic term as the lowest order, in sharp contrast to its electron counterpart in which the leading term is a $\mathbf{k}$-linear.

The necessary ingredients to get Rashba splitting are atomic spin-orbit coupling , and an asymmetric potential in the direction perpendicular to the 2D surface. The main effect of the symmetry breaking potential is to open a band gap between the isotropic and the , bands. The secondary effect of this potential is that it hybridizes the with the.

We propose and formulate an interaction induced staggered spin-orbit order as a new emergent phase of two-dimensional Fermi gases. We show that when some form of inherent spin-splitting via Rashba-type spin-orbit coupling renders two helical Fermi surfaces to become signiﬁcantly 'nested', a Fermi surface instability arises. Dec 03, 2018 · We identified a scalable way to transduce the spin state of a nanomagnet to a charge state via spin–orbit effects 19,20,21,22,23,24,25,26,33,34,35,36, such as the interface Rashba–Edelstein.

PDF Tunneling conductance of a two-dimensional electron gas with Rashba.

The Rashba spin–orbit coupling has a similar energy band splitting, but the asymmetry comes either from the bulk asymmetry of uniaxial crystals (e.g. of wurtzite type) or the spatial inhomogeneity of an interface or surface. Dresselhaus and Rashba effects are often of similar strength in the band splitting of GaAs nanostructures. Spin-orbit interaction (SOI) can control the electrical influence of the spin degree of freedom by transferring the orbital angular momentum taken by an electric current to the electron spin. Spin-orbit coupling (SOC), particularly Rashba spin-orbit coupling (RSOC), plays a key role in the well-known Hall effect [5, 6].

The Rashba effect, similarly to the Dresselhaus effect, is a band splitting due to spin-orbit coupling that appears in systems with broken inversion symmetry. While the Rashba effect appears in low dimensional systems (films, heterostructures) and uniaxial bulk systems, the Dresselhaus effect is observed in cubic bulk.

This theoretical Perspective reviews spin-orbit coupling (SOC), including the Rashba effect and Dresselhaus effect, in two-dimensional (2D) semiconductors. We first introduce the origin of the Rashba effect and Dresselhaus effect using the Hamiltonian models; we then summarize 2D Rashba semiconductors predicted by first-principles density functional theory (DFT) calculations, including AB. For the linear Rashba SO coupling of the semiconductor conduction band can reproduce the behavior of more sophisticated eight-band k ·p model calculations. This is achieved by adjusting a single effective parameter that depends on the nanowire crystal structure and its chemical composition. We further compare our results to the. We report a tunable and enhanced interface-induced Rashba spin-orbit coupling where the spin relaxation mechanism varies with magnetic behavior of the underlying ${\mathrm{LaMnO}}_{3}$ layer.

May 25, 2022 · Spin orbit coupling (SOC) with mechanisms such as spin current generation via the spin Hall effect (SHE) (Fig. 1a) or non-equilibrium spin accumulation at the surface or interface with inversion symmetry breaking via the Rashba–Edelstein effect (Fig. 1b) can give rise to a new family of torques, namely, spin orbit torques (SOTs), thereby providing a new route to novel spintronic devices. The spin-orbit coupling parameter, which can be tuned by applying an external gate voltage perpendicular to the 2D plane, and the components of are the Pauli spin matrices.

Modulated Rashba spin-orbit coupling. When the period of the modulation becomes commensurate with the band ﬁlling, the Rashba coupling drives a quantum phase transition to a nonmagnetic insulating state. Using bosonization and a renormalization-group approach, we ﬁnd that this state is robust against electron-electron interactions.
