We study theoretically the spin-Hall effect as well as its reciprocal phenomenon (a transverse charge current driven by a spin-dependent chemical potential gradient) in electron and hole finite size mesoscopic systems. the landauer-buttiker-keldysh formalism is used to model samples with mobilities and rashba coupling strengths which are experimentally accessible and to demonstrate the appearance of measurable charge currents induced by the spin-dependent chemical potential gradient in the re...We study theoretically the spin-Hall effect as well as its reciprocal phenomenon (a transverse charge current driven by a spin-dependent chemical potential gradient) in electron and hole finite size mesoscopic systems. the landauer-buttiker-keldysh formalism is used to model samples with mobilities and rashba coupling strengths which are experimentally accessible and to demonstrate the appearance of measurable charge currents induced by the spin-dependent chemical potential gradient in the reciprocal spin-hall effect. we also demonstrate that within the mesoscopic coherent transport regime the onsager relations are fulfilled for the disorder averaged conductances for electron and hole mesoscopic systems.» weiterlesen» einklappen
