Resumen
The ultrafast relaxation kinetics of photoinjected plasmas in blue-emitting highly-polar III-nitrides is analysed. The evolution of the nonequilibrium thermodynamic state of the 'hot carriers' and 'hot phonons' is studied. It is shown that the dissipative phenomena are orders of magnitude larger than in less strongly polar materials, such as GaAs. Moreover, the phenomena of 'phonon bottleneck' and 'hot-phonon temperature overshoot' are characteristically enhanced. 38 19 3584 3589
