Summary

The intrinsic spin Hall effect arises from local electronic structure, not transport phenomena. It generates equal and opposite orbital angular momentum currents, preventing spin accumulation at sample edges.

Area of Science:

  • Condensed matter physics
  • Materials science
  • Spintronics

Background:

  • The spin Hall effect (SHE) is crucial in spintronics for converting charge currents into spin currents.
  • Understanding the origins of SHE, particularly the intrinsic versus extrinsic contributions, is key to its applications.
  • Existing models often treat intrinsic and extrinsic SHE separately, leading to potential ambiguities.

Purpose of the Study:

  • To introduce a generalized definition for intrinsic and extrinsic transport coefficients.
  • To clarify the fundamental nature of the intrinsic spin Hall effect.
  • To investigate the relationship between intrinsic spin Hall current and orbital angular momentum Hall current.

Main Methods:

  • Theoretical derivation of generalized transport coefficients.
  • Analysis of electronic structure contributions to transport phenomena.
  • Mathematical proof of current conservation and spin accumulation.

Main Results:

  • Intrinsic transport coefficients are determined solely by local electronic structure.
  • The intrinsic spin Hall effect is not a transport phenomenon but an electronic structure effect.
  • Intrinsic spin Hall current is intrinsically coupled to an opposite orbital angular momentum Hall current.
  • The intrinsic spin Hall effect does not lead to spin accumulation at edges or interfaces.

Conclusions:

  • The generalized definition provides a unified framework for understanding transport coefficients.
  • The intrinsic spin Hall effect's origin in electronic structure has significant implications for spintronics device design.
  • The inherent coupling to orbital angular momentum currents and lack of spin accumulation necessitate revised theoretical approaches.
