Abstract
Two different processes of quasi-two-dimensional exciton dynamics involving acoustic phonons are studied for semiconductor quantum wells. The first process involves the scattering of an exciton from an initial state to a final state through three different channels and the second process involves the decay of an exciton into a free-electron-hole pair by absorption of an acoustic phonon. Rates for both processes are calculated using a variational wave function for the two-dimensional exciton. The calculated results agree quite well with recent experimental results.
