Comparison of exciton-biexciton with bound exciton-biexciton dynamics in GaN: Quantum beats and temperature dependence of the acoustic-phonon interaction
The polarization dependence of biexcitonic signals and quantum beats between A-excitons (XA) and A-biexcitons (XAXA) in a high-quality GaN epilayer is measured by spectrally-resolved and time-integrated four-wave mixing. With cross-linear polarised light, mixed beats with two periods are observed: t...
