Polaron and Soliton Lattices Within One-Particle Models of Conducting Polymers with a Degenerate Gropotential a first order phase transition from a soliton lattice (stable at low concentrations) to a polaron lattice (stable at high doping level) near 5% doping content can be obtained. Consequences for polymers with a nondegenerate ground state are briefly discussed.作者: Cardiac-Output 時間: 2025-3-23 09:30
Interpretation of the Photoinduced Infrared Spectra of Oriented Polyacetylene and Triblock Copolymermination of the photoinduced localized vibrational modes. The bimodal distribution of conjugated segments, derived from Raman data, is then used to weigh the vibrational contribution to the photoinduced broad band from the different segments. All experimental data presented here are therefore interpreted with such a model.作者: 搜尋 時間: 2025-3-23 11:04

A screened version of the Ohno effective Coulomb potential is used in parallel to the usual Ohno potential in order to incorporate the additional screening due to electrons on neighboring chains. This screening is observed to cause a more localized excitation, i.e. to increase the electron-hole interaction.作者: 異端邪說下 時間: 2025-3-24 05:27 作者: 莊嚴(yán) 時間: 2025-3-24 06:31 作者: hysterectomy 時間: 2025-3-24 13:12 作者: Fortuitous 時間: 2025-3-24 17:17 作者: 引起 時間: 2025-3-24 22:55

A non-monotonic dependence of the relaxation rate on this coupling constant is found mainly due to the emergence of new bound states inside the energy gap. Similar phenomena may occur for other quasi-one-dimensional systems.作者: Herpetologist 時間: 2025-3-29 01:54
