Electrical measurement of the direct spin hall effect in Fe/InxGa(1-x)As heterostructures.
We report on an all-electrical measurement of the spin Hall effect in epitaxial Fe/InxGa(1-x)As heterostructures with n-type (Si) channel doping and highly doped Schottky tunnel barriers. A transverse spin current generated by an ordinary charge current flowing in the InxGa(1-x)As is detected by measuring the spin accumulation at the edges of the channel. The spin accumulation is identified thr...
متن کاملThe Quantum Spin Hall Effect
Most quantum states of condensed matter are classified by the symmetries they break. For example, crystalline solids break translational symmetry, and ferromagnets break rotational symmetry. By contrast, topological states of matter evade traditional symmetrybreaking classification schemes, and they signal the existence of a fundamentally different organizational principle of quantum matter. Th...
متن کاملOptical spin hall effect.
A remarkable analogy is established between the well-known spin Hall effect and the polarization dependence of Rayleigh scattering of light in microcavities. This dependence results from the strong spin effect in elastic scattering of exciton polaritons: if the initial polariton state has a zero spin and is characterized by some linear polarization, the scattered polaritons become strongly spin...

مطالعه حاضر تلاشی است برای بررسی تأثیرات به کارگیری فرهنگ لغات ، یکی از مهمترین ابزارهای یادگیری واژگان درفراگیری زبان خارجی، بر روی دانش لغوی. دراین تحقیق فرهنگ های الکترونیکی در قیاس با فرهنگ های چاپی مورد بررسی قرارگرفته اند که آیا این فرهنگ ها تاثیرقابل توجهی بر روی دوبعد کمی و کیفی دانش لغوی یعنی عمق و گستره لغات می گذارند. همچنین مشخص گردیده است که آیا تفاوت قابل ملاحظه ای میان عمق و گستر...
15 صفحه اولSpin Hall drag in electronic bilayers.
We predict a new effect in electronic bilayers: spin Hall drag. The effect consists of the generation of spin accumulation across one layer by an electric current along the other layer. It arises from the combined action of spin-orbit and Coulomb interactions. Our theoretical analysis, based on the Boltzmann equation formalism, identifies two main contributions to the spin Hall drag resistivity...
