EFFECT OF ELECTRON-PHONON INTERACTION ON ELECTRON SPIN POLARIZATION IN A QUANTUM DOT LIGHT EMITTING DIODE
This paper presents a theoretical model for the effect of electron-phonon interaction, temperature and
magnetic field on degree of electron spin polarization in GaAs/InAs quantum dot LED. To describe the
dynamics, quantum Langevin equation for photon number and carrier number is used. Simulation results
show that degree of electron spin polarization in quantum dot decreases with increase of electron phonon
interaction parameter at constant temperature and constant magnetic field which agrees with experimental
results in literatures
