Abstract
Optical phonon modes in a semiconductor quantum dot were analyzed with exactly solvable model structure. A set of universal formulae for the electron and phonon wave functions was derived for spheroids. Using these wavefunctions, the intersubband scattering rates due to emission of phonons were investigated as a function of the size and the shape of the dot. It was shown that the maximum total scattering rate is slightly enhanced by reducing the height of the dot, which is attributed to the increase of the contribution of the interface modes.
