ABSTRACT
Fast and slow photocarrier dynamics in indium nitride films have been investigated using femtosecond transient measurements at room temperature. The behavior of the decay dynamics is found to be strongly dependent on the excitation energy and the background carrier density. We have found that the slow decay component disappears under optimized conditions due to equilibrium between band filling and bandgap renormalization effects.

    The electron mobility of In-Ga-Zn-oxide (IGZO) is known to be enhanced by higher In content. We theoretically investigated the mobility-enhancement mechanism by proposing an In-Ga-Zn-disorder scattering model for an In-rich crystalline IGZO (In1+xGa1-xO3(ZnO)m (0 < x < 1, m > 0)) thin film. The...
