Summary

We derived transport equations for 2D electron systems with Rashba spin-orbit interaction and disorder. Our findings show electric-field induced spin accumulation and spin current, with vanishing spin-Hall conductivity in infinite systems.

Area of Science:

  • Condensed matter physics
  • Spintronics
  • Mesoscopic physics

Background:

  • Two-dimensional electron systems (2DES) are crucial for modern electronics.
  • Rashba spin-orbit interaction (RSOI) and disorder are key factors influencing electron behavior in 2DES.
  • Understanding spin transport is vital for developing spintronic devices.

Purpose of the Study:

  • To derive and analyze transport equations for 2DES with RSOI and disorder.
  • To investigate electric-field induced spin accumulation and spin current.
  • To determine the impact of RSOI and scattering on spin transport properties.

Main Methods:

  • Derivation of coupled diffusion equations for electron density and spin in the slow spatial variation limit.
  • Analytical calculation of spin accumulation and spin current in finite-size samples.
