Franz-Keldysh effect in epitaxial ZnO thin films
(American Institute of Physics, 2018-02)
Photoconductance spectroscopy has been studied in epitaxial ZnO thin films with different thicknesses that range between 136 and 21 nm. We report a systematic decrease in photoconductivity and a red shift in band edge ...
Photoelectrochemical response and photoconductivity of poly(3-methylthiophene)
(Pergamon-elsevier Science LtdOxfordInglaterra, 1998)
Wavelength dependence of the photo-electromotive-force effect in CdTe:V crystal with bipolar photoconductivity
(Elsevier B.V.Science Direct, 2007)
Electron scattering and effects of sources of light on photoconductivity of SnO2 coatings prepared by sol-gel
(Elsevier B.V., 1999-05-01)
Electro-optical properties of sol-gel derived 2 mol% antimony or niobium doped tin dioxide films have been measured. The electron density has been calculated considering all the relevant scattering mechanisms and experimental ...

Excitation spectrum for ultrafast photogeneration of charged solitons in polyacetylene
(Elsevier B.V., 2003-04-04)
Ultrafast photoinduced absorption by IRAV modes is used to detect charged solitons in oriented polyacetylene. We find that soliton pairs are photogenerated within our time resolution of similar to250 fs with similar to100% ...
Oxygen partial pressure dependence of electrical conductivity in γ′-Bi2MoO6
(Academic Press Inc Elsevier Science, 2008-05)
The electrical conductivity of γ′-Bi2MoO6 was surveyed between 450 and 750 °C as a function of oxygen partial pressure, in the range 0.01-1 atm. A -frac(1, 6) power law dependence, consistent with a Frenkel defect model ...
Contribution of oxygen related defects to the electronic transport in SnO2 sol-gel films
(2001-01-01)
SnO2 deposited by sol-gel is a polycrystalline film with small grain size. Oxygen present at a less grain boundary traps electrons and then the depletion layer around the potential barrier of the grain boundary becomes ...
