Breathers and Photoinduced Absorption in Polyacetylene
'The dynamics of trans-polyacetylene is studied within the adiabatic model of Su, Schrieffer, and Beeper. A single soliton has a maximum velocity, v, which can be higher than the sound velocity. A long-time simulation shows that, from an initial electron-hole pair, a soliton and antisoliton emerge with velocities +v and that a persistent breather is left behind. 'This breather may account for t...
متن کاملPhotoinduced Absorption from Localized Intra-gap States
A model is developed for photoinduced absorption from localized states observed in femtosecond pump-probe experiments in high-Tc superconductors and other materials. The dynamics of localized carriers are described in terms of phenomenological approach similar to that originaly proposed by Rothwarf and Taylor. Expanding the relaxation rate in powers of the order parameter we have shown that den...
متن کاملCharacteristics of gastrointestinal absorption of DX-9065a, a new synthetic anticoagulant.
DX-9065a, a newly synthesized anticoagulant that selectively inhibits factor Xa, is a zwitterion and has characteristics of high water solubility and low lipophilicity. We predicted the fraction absorbed (Fa) of DX-9065a to be approximately 15-35% in humans, based on the boundary layer theory using the intestinal perfusion method in rats. However, human oral bioavailability was 2-3% in clinical...
متن کاملTransient Photoinduced Absorption in Ultrathin As-grown Nanocrystalline Silicon Films
We have studied ultrafast carrier dynamics in nanocrystalline silicon films with thickness of a few nanometers where boundary-related states and quantum confinement play an important role. Transient non-degenerated photoinduced absorption measurements have been employed to investigate the effects of grain boundaries and quantum confinement on the relaxation dynamics of photogenerated carriers. ...
متن کاملPhotoinduced absorption spectroscopy of dye-sensitized nanostructured TiO2
Photoinduced absorption (PIA) spectroscopy was used to investigate dye-sensitized electrodes and solar cells under illumination conditions comparable to sunlight. In the absence of redox electrolyte, cis-RuðdcbpyÞ2ðNCSÞ2-sensitized nanostructured TiO2 films show a long-lived photoinduced charge-separation (oxidized dye molecules/injected electrons in TiO2), with a lifetime of about 10 3 s under...
