Investigation of temperature influence on photo-induced conductivity in n-type AlxGa1-xAs
(1998-12-01)
We present conductance as function of temperature (G×T) under influence of monochromatic light in the range 0.5-1.5 μm for direct as well as indirect bandgap n-type AlxGa1-xAs. Results obtained below 60 K in indirect bandgap ...

Integration of processes induced air flotation and photo-Fenton for treatment of residual waters contaminated with xylene
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Produced water in oil fields is one of the main sources of wastewater generated in the industry. It contains several organic compounds, such as benzene, toluene, ethyl benzene and xylene (BTEX), whose disposal is regulated ...
Photo-Fries rearrangement of aryl acetamides: regioselectivity induced by the aqueous micellar green environment
(Royal Society of Chemistry, 2016-01)
Photochemical reactions tend to give more than one photoproduct. However, such a reaction can be a powerful synthetic tool when it is possible to conduct it in regioselective conditions yielding a single photoproduct. ...
Electron trapping in the photo-induced conductivity decay in GaAs/SnO2 heterostructure
(2018-06-01)
The decay of photo-induced conductivity is measured for GaAs/SnO2 heterostructure, after illumination with appropriate wavelength. The top oxide layer is deposited by sol–gel-dip-coating and doped with Eu3+, and the GaAs ...
Decay of photo-induced conductivity in Sb-doped SnO2 thin films, using monochromatic light of about bandgap energy
(2013-02-15)
Doping tin dioxide (SnO2) with pentavalent Sb5+ ions leads to an enhancement in the electrical conductivity of this material, because Sb5+ substitutes Sn4+ in the matrix, promoting an electronic density increase in the ...

Photo-Induced Conductivity of Heterojunction GaAs/Rare-Earth Doped SnO2
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2013-07-01)
Rare-earth doped (Eu3+ or Ce3+) thin layers of tin dioxide (SnO2) are deposited by the sol-gel-dip-coating technique, along with gallium arsenide (GaAs) films, deposited by the resistive evaporation technique. The as-built ...
