Spintronics is aimed at actively controlling and manipulating the spin degrees of freedom in semiconductor devices. A promising way to achieve this goal is to make use of the tunable Rashba effect that relies on the spin-orbit interaction in a two-dimensional electron system immersed in an inversion-asymmetric environment. The spin-orbit-induced spin splitting of the two-dimensional electron st...

Recent interest in the field of “spintronics” stems primarily from the desire to use the spin degree of freedom of a single electron, or a collection of electrons, to store, process, detect and communicate information. Digital information (in the form of binary bits 0 and 1) is encoded in the spin polarization of electron(s), then “processed” using spin-spin or spin-orbit interactions, subseque...

In semiconductor spintronics, electron spin rather than charge is the key property. This paper describes several spin-related devices using spin-orbit interaction. We have experimentally confirmed that the spin-orbit interaction in a semiconductor two-dimensional electron gas channel can be controlled by a gate voltage. This is the first step towards the creation of functional spin devices. The...

in this study, tio2 and zno nanofilms were prepared by sol-gel spin-coating method. nanofilms were characterized by x-ray diffraction (xrd), energy dispersive analysis of      x-ray (edx), scanning electron microscopy (sem) and field emission scanning electron microscopy (fe-esm). structural and morphological properties of nanofilms were investigated. the average crystalline size of tio2 and zn...

Boundary conditions are derived that determine the penetration of spin current through an interface of two non-collinear ferromagnets with an arbitrary angle between their magnetization vectors. We start from the well-known transformation properties of an electron spin wave functions under the rotation of a quantization axis. It allows directly find the connection between partial electric curre...

We present analysis of the interacting quantum wire problem in the presence of magnetic field and spin-orbital interaction. We show that an interesting interplay of Zeeman and spin-orbit terms, facilitated by the electron-electron interaction, results in the spin-density wave (SDW) state when the magnetic field and spin-orbit axes are orthogonal. We explore consequences of the spin-orbit intera...

The key role that entanglement plays in quantum information processing has been investigated over the past few years [1]. In this framework, the role that it plays in quantum transport in mesoscopic systems has been analyzed [2]. Recently, we have shown a novel way in which entanglement can be used for controlling electron transport in nanostructures [3]. Assume that we have a 1D wire, where tw...

Theory predicts for the two-dimensional electron gas with only a Rashba spin-orbit interaction a vanishing spin Hall conductivity and at the same time a finite inverse spin Hall effect. We show how these seemingly contradictory results are compatible with the Onsager relations: The latter do hold for spin and particle (charge) currents in the two-dimensional electron gas, although (i) their for...

A molecular spin quantum computer (MSQC) requires electron spin qubits, which pulse-based electron spin/magnetic resonance (ESR/MR) techniques can afford to manipulate for implementing quantum gate operations in open shell molecular entities. Importantly, nuclear spins, which are topologically connected, particularly in organic molecular spin systems, are client qubits, while electron spins pla...
