| Description: | The electron{acoustic-phonon scattering process in spherical II-VI quantum dots is discussed. The quantized acoustic modes are described in terms of the Lamb's classical theory. We considered two mechanism for the interaction between electrons and acoustic modes: microscopic deformation potential, and macroscopic acoustic deformation, also called the ripple mechanism. We also discuss the in uence of the glass matrix on the electron-phonon coupling. Our calculations show that the ripple mechanism scattering rates become dominant by more than an order of magnitude, for small dot radius. In general, the total scattering rate depends on the acoustical properties of the glass matrix. |
