摘要：
In this report the differences and identities of charge carrier drift by measuring drift of photo-excited carriers according to subnanosecond TOF integral mode are compared to drift of equilibrium carriers investigated by CELIV method in thin (0.1 - 1.1 mum) layers of poly(p-phenylene vinylene) (PPV) polymer. From TOF measurements we obtained that the very initial mobility of photogenerated holes relaxes from the value of the order of 10 (-2) cm(2)/Vs down to the values of the order of 10 (-5) cm(2)/Vs within nanosecond time duration.
