Orientational relaxation in a dispersive dynamic medium : Generalization of the Kubo-Ivanov-Anderson jump diffusion model to include fractional environmental dynamics
K. Seki, B. Bagchi, M. Tachiya
Ivanov-Anderson (IA) model (and an earlier treatment by Kubo) envisages a decay of the orientational correlation by random but large amplitude molecular jumps, as opposed to infini…
Dispersive diffusion controlled distance dependent recombination in amorphous semiconductors
Kazuhiko Seki, Mariusz Wojcik, M. Tachiya
The photoluminescence in amorphous semiconductors decays according to power law at long times. The photoluminescence is controlled by dispersive transport of electrons…
Dispersive photoluminescence decay by geminate recombination in amorphous semiconductors
Kazuhiko Seki, K. Murayama, M. Tachiya
The photoluminescence decay in amorphous semiconductors is described by power law at long times. The power-law decay of photoluminescence at long times is commonly obs…
Fractional Reaction-Diffusion Equation
Kazuhiko Seki, Mariusz Wojcik, M. Tachiya
A fractional reaction-diffusion equation is derived from a continuous time random walk model when the transport is dispersive. The exit from the encounter distance, which is descri…
