Intersubband absorption linewidth in GaAs quantum wells due to scattering by interface roughness, phonons, alloy disorder, and impurities
Takeya Unuma, Masahiro Yoshita, Takeshi Noda +2
We calculate the intersubband absorption linewidth in quantum wells (QWs) due to scattering by interface roughness, LO phonons, LA phonons, alloy disorder, and ionized impurities,…

Electron--Electron Scattering in Quantum Wires and it's Possible Suppression due to Spin Effects
Gerhard Fasol, Hiroyuki Sakaki
A microscopic picture of electron-electron pair scattering in single mode quantum wires is introduced which includes electron spin. A new source of `excess' noise for hot carriers…

Spontaneous Spin-Polarization of Ballistic Electrons in Single Mode Quantum Wires due to Spin-Splitting
Gerhard Fasol, Hiroyuki Sakaki
We show that a quantum wire device with spin splitting can work as an active spin polarizer. Hot electrons in one `spin' subband (e.g. `spin-up') may pass such a device with weak e…
