Abstract
We calculate scattering rates of intrasubband and intersubband electro nic transitions in asymmetric single quantum wells (QW's) and step QW' s due to interface phonons, confined bulk-like LO phonons, and half-sp ace LO phonons. The relative importance of the different phonon modes is analyzed. The results show that the electron-phonon scattering rate s have intimate relation to the QW parameters.
