Electron-phonon interactions in multi-component hole gas plasma in polar semiconductors: from bulk to quantum dot structures
We study hole-phonon interactions as well as charge and spin scattering mechanisms from hole gas fluctuations including their overlapping with phonon features by using near infrared excitation of doped bulk p-GaAs and by self-assembled InAs/GaAs quantum dot structures. Theoretical arguments a...

| Sumario: | We study hole-phonon interactions as well as charge and spin scattering mechanisms
from hole gas fluctuations including their overlapping with phonon features by using near
infrared excitation of doped bulk p-GaAs and by self-assembled InAs/GaAs quantum dot
structures. Theoretical arguments and experimental evidence of acoustic plasmon existence
are presented. |
