Paper Abstract

Biexciton lifetime is studied in wide wavenumber regions, high from 0.887 to 6.2 X 106 cm-1 and low from 0 to 0.2 X 106 cm-1. In both regions its lifetime is found within about 20 approximately 40 ps, although it decays via different intermediate states, i.e. emitting different branch polaritons. In the high wavenumber region the lifetime becomes shorter with wavenumber. The decay rates responsible for the radiative emission, acoustic phonon spontaneous emission and elastic scatterings are derived.
