 | Boehme, Christoph | Experimental discrimination of geminate and non-geminate recombination in a-Si:H | A study of charge-carrier recombination in intrinsic hydrogenated amorphous silicon (a-Si:H) is presented using pulsed electrically and pulsed optically detected magnetic-resonance spectroscopies in order to measure the influence of spin-dependent recombination on photoluminescence (PL) and photoc... | Geminate recombination | 2009-05 |

 | Vardeny, Zeev Valentine | Studies of picosecond carrier dynamics in polysilane alloys: evidence for geminate recombination in small hydrogenated amorphous silicon clusters | The ultrafast photocarrier dynamics in polysilane alloys amorphous (SiH2)n' has been studied using the picosecond photoinduced absorption (PA) technique. For excitation below the optical gap, the PA response decays exponentially and is faster at low temperatures. This is interpreted in terms of e-h ... | Picosecond carrier dynamics; Polysilane alloys; Geminate recombination; a-Si:H; Amorphous silicon; Ultrafast relaxation; Photoexcited carriers | 1990 |

 | Lupton, John Mark | Ultrafast dynamics of charge carrier photogeneration and geminate recombination in conjugated polymer: fullerene solar cells | We investigate the nature of ultrafast exciton dissociation and carrier generation in acceptor-doped conjugated polymers. Using a combination of two-pulse femtosecond spectroscopy with photocurrent detection, we compare the exciton dissociation and geminate charge recombination dynamics in blends ... | Ultrafast dynamics; Charge carrier photogeneration; Geminate recombination; Exciton dissociation; Acceptor-doped; MeLPPP; MDMO-PPV | 2005-11 |
