Organic-to-inorganic structural chirality transfer in a 2D hybrid.

The spintronic field effect transistor harnesses the so-called Rashba or Dresselhaus spin-orbit coupling effect, which suggests that one can control electron spin by electric field. Although the method holds promise for efficient and high-speed computing, certain challenges must be overcome before the technology reaches its true, miniature but. Coupling to a magnetic impurity17.

Interplay of the Rashba and Dresselhaus spin-orbit coupling in the optical spin susceptibility of 2D electron systems. By Catalina Lopez-Bastidas. The influence of cavity photons on the transient transport of correlated electrons through a quantum ring with magnetic field and spin-orbit interaction. The spin splitting in GaN-based heterostructures has been investigated by means of circular photogalvanic effect experiments under uniaxial strain. The ratios of Rashba and Dresselhaus spin-orbit coupling coefficients (R/D ratios) have been measured in Al x Ga 1 − x N / GaN heterostructures with various Al compositions. It is found that the R/D ratio increases from 4.1 to 19.8 with the Al.

The spintronic field effect transistor harnesses the so-called Rashba or Dresselhaus spin-orbit coupling effect, which suggests that one can control electron spin by electric field. Although the method holds promise for efficient and high-speed computing, certain challenges must be overcome before the technology reaches its true, miniature but. We study effects of the oft-neglected cubic Dresselhaus spin-orbit coupling (i.e., directly proportional p3) in GaAs/AlGaAs quantum dots. Using a semiclassical billiard model, we estimate the magnitude of the spin-orbit induced avoided crossings in a closed quantum dot in a Zeeman field. Using previ.

Abstract Considering Dresselhaus-type spin-orbit coupling (SOC), we theoretically investigate spin-polarized transport in a 3-layered semiconductor heterostructure, InSb/InxGa1-xAs/GaSb. Adopting improved transfer matrix method to solve Schrodinger equation, electronic transmission coefficient is obtained exactly, and then spin polarization ratio is evaluated.

We study the effects caused by Rashba and Dresselhaus spin-orbit coupling over the thermoelectric transport properties of a single-electron transistor, viz., a quantum dot connected to one-dimensional leads. Using linear response theory and employing the numerical renormalization group method, we calculate the thermopower, electrical and thermal conductances, dimensionless thermoelectric.

They have the lowest energy and are separated from the remaining eigenstates by a gap determined by the Rabi frequencies of the atom-light coupling. Adiabatically eliminating the excited states, the resulting Hamiltonian of the remaining two internal states in- cludes either Rashba or Dresselhaus spin-orbit (SO) coupling.

Here, we simulate spin-orbit interactions in a tunable, liquid crystal (LC)-filled, optical cavity. By controlling the refractive index anisotropy of the intracavity layer, we adiabatically engineer the coupling between optical modes and show that the system is described by a Hamiltonian with Dresselhaus and Bychkov-Rashba (3, 4) terms, originally used to describe fermions. In this paper, Dresselhaus spin-orbit coupling (SOC) modulating quantum pumps driven by triple time-dependent potentials are investigated, where the pump center are semiconductors connected to two.

Keywords: Ultracold atoms, light-induced gauge potentials, Rashba-Dresselhaus spin-orbit coupling 1. INTRODUCTION Spin-orbit (SO) coupling of the Rashba1 3 or Dresselhaus4,5 type has been widely studied in condensed matter physics. Such SO coupling linear in momentum is equivalent to non-abelian vector potentials built from the spin-1/2 Pauli.

A particular group of angular momentum states contains degenerate modes which are strongly coupled via the Dresselhaus Hamiltonian, which results in a significant energy splitting with increasing momentum. Hence, under certain conditions Dresselhaus spin-orbit coupling is relevant for [111] InAs and [111] InSb nanowires.

The authors have investigated the zero-frequency shot noise of current through resonant double-barrier structures. Taking into account the spin-orbit coupling (SOC) effect, general expressions for the shot noise in fully phase-coherent mesoscopic conductors are derived based on the scattering approach. It is found that the Dresselhaus SOC can greatly affect the average current I, shot noise S.

When only one type of spin-orbit coupling, e.g., the Dresselhaus spin-orbit coupling linear in the wave vector, exists in the system, this th-eoretical approach allows an analytical solution. This is the case in narrow AlAs quantum wells. The corresponding theoretical curve is shown in Fig. 2a. The spintronic field effect transistor harnesses the so-called Rashba or Dresselhaus spin-orbit coupling effect, which suggests that one can control electron spin by electric field. Although the method holds promise for efficient and high-speed computing, certain challenges must be overcome before the technology reaches its true, miniature but.

The Rashba and Dresselhaus types of spin-orbit coupling are two typical linear coupling forms. We establish the fundamental physics of a model which can be viewed as the double version of the Rashba and Dresselhaus spin-orbit coupling.
