摘要: The energy relaxation time of hot carriers photoexcited in bulk InGaN is measured. time-resolved pump and probe transmission measurements with subpicosecond resolution show that the hot-carrier 0.92 ps at 15 K. becomes significantly shorter higher temperatures. At temperatures than 150 K, there are no meaningful differences between rise times. This strong temperature dependence indicates electron-phonon scattering dominates carrier process.
