The phase relaxation time of biexcitons Tb2bi and that of excitons T2ex in a bulk ZnO have been measured by the use of femtosecond four-wave mixing as functions of excitation wavelength, excitation power, and temperature. The biexciton-acoustic phonon interaction coefficient has been determined to be Βacbi ≈ 53/µeV/K as an average value. For A excitons, the interaction coefficients with acoustic and optical phonons have been determined to beΒacex≈ 8.4 µeV/K and Βoptex ≈ 14 meV, respectively. [ABSTRACT FROM AUTHOR] |
