| 초록 |
We prepared well-defined hierarchical structures comprising doubly open-ended TiO2 nanotube (NT) arrays covered with various layers of few-nm sized TiO2 nanoparticles (NPs) to investigate the electron collection mechanisms in homogeneous hybrid structures. We found that competitive electron transport pathways (direct transport through the NT and randomized transport through the NPs) are present in the homogeneous hybrid structures. Photoinduced electrons generated at the few-nm sized TiO2 NPs directly connected with TiO2 NTs (e.g., isolated and single layered NPs on the surface of NTs) dominantly traveled to the NTs. With increasing the number of TiO2 NP layers, photoinduced electrons are randomly transported through the TiO2 NP layers. |
