Unpolarized current in electron-doped GaAs and InP becomes unstable at high electric fields, dynamically forming spin-polarized current pulses. This spontaneous generation occurs due to differing conductivity between spin-polarized and unpolarized electron gases.

Area of Science:

  • Semiconductor physics
  • Spintronics

Background:

  • Electron-doped Gallium Arsenide (GaAs) and Indium Phosphide (InP) are key materials in semiconductor research.
  • Understanding current dynamics in these materials at high electric fields is crucial for device applications.

Purpose of the Study:

  • To predict the behavior of unpolarized current in electron-doped GaAs and InP under high electric fields.
  • To investigate the spontaneous generation of spin-polarized current pulses.

Main Methods:

  • Theoretical prediction of current flow dynamics.
  • Analysis of electron gas conductivity differences.

Main Results:

  • Unpolarized current is predicted to be unstable at high electric fields.

  • Dynamic formation of spin-polarized current pulses is observed.
  • Spontaneous generation of spin-polarized current occurs due to conductivity differences, independent of spin-orbit interaction.

    • Conclusions:

    • Electron-doped GaAs and InP exhibit dynamic spin-polarized current pulse formation at high electric fields.
    • This phenomenon is driven by intrinsic conductivity variations in electron gases.
    • External magnetic fields can influence pulse alignment but are not essential for generation.
