title = "Picosecond spin relaxation of acceptor-bound exciton in wurtzite GaN",
abstract = "The spin relaxation process of acceptor-bound excitons in wurtzite GaN is observed by spin-dependent pump and probe reflectance measurement with subpicosecond time resolution. The time evolutions measured at 15-50 K have a single exponential component corresponding to spin relaxation times of 1.40-1.14 ps. The spin relaxation time, τs, is found to be proportional to T-0.175, where T is the temperature. This temperature dependence is quite weak compared with that of A-band free excitons showing τ ≅ T-1.41 at 150-225K.",
