Enhanced electrical property of nanostructured Sb-doped SnO2 thin film processed by soft chemical method
(Elsevier B.V., 2004-02-02)
The effect of the Sb addition on the microstructural and electrical conductivity of the SnO2 thin film was studied in this work. Experimental results show that the Sb addition allowed to control the grain size and electrical ...
Effect of the excess of bismuth on the morphology and properties of the BaBi2Ta2O9 ceramics
(Elsevier B.V., 2005-03-01)
In this study, the effect of bismuth content on the crystal structure, morphology and electric properties of barium-bismuth-tantalate (BBT) ceramics was explored with the aid of X-ray diffraction (XRD), scanning electron ...
Glossary of terms relating to electronic, photonic and magnetic properties of polymers (IUPAC Recommendations 2021)
(2022-01-01)
These recommendations are specifically for polymers and polymer systems showing a significant response to an electromagnetic field or one of its components (electric field or magnetic field), i.e., for electromagnetic-fi ...
Structural electrical and optical properties of undoped and indium doped ZnO thin films prepared by the pyrosol process at different temperatures
(Elsevier B.V., 2002-09-02)
The influence of the substrate temperature on the structural features and opto-electrical properties of undoped and indium-doped ZnO thin films deposited by pyrosol process was investigated. The addition of indium induces ...
Barrier, mechanical and conductive properties of polycaprolactam nanocomposites containing carbon based particles: effect of the kind of particle
(Elsevier, 2017)
In this study, polycaprolactam (PA6) nanocomposites with thermally reduced graphene oxide (TrGO) and
carbon nanotubes (CNTs) were prepared by melt blending with the aim of obtaining films with improvements
in permeability ...
Effect of oxidizing and reducing atmospheres on the electrical properties of dense SnO2-based varistors
(Elsevier B.V., 2001-02-01)
The SnO2 based varistor systems recently presented in the literature appear to have a promising potential in commercial applications. Experimental evidence shows that there is a dependence of nonlinear constant values with ...
Effect of La2O3 addition and O-2 atmosphere on the electric properties of SnO2TiO2
(Elsevier B.V., 2005-04-15)
The electric properties of (Sn, Ti)O-2 doped with 1.00 mol% CoO, 0.05 mol% Nb2O5 and xmol% La2O3 (0.25 less than or equal to x less than or equal to 1.00) have been studied. Sn0.25Ti0.75Co0.01Nb0.005 doped with 0.50 mol% ...
Electrical and microstructural properties of CaTiO3-doped K1/2Na1/2NbO3-lead free ceramics
(Indian Acad Sciences, 2011-10-01)
Microstructure, electrical properties and dielectric behaviour of K1/2Na1/2NbO3 (KNN) and CaTiO3-modified K1/2Na1/2NbO3 (CTO-KNN) systems, were investigated. Discs doped with 0 to 0-55% mol of CaTiO3 (CTO) were sintered ...
Grain size effect on the electrical response of SnO2 thin and thick film gas sensors
(ABM, ABC, ABPol, 2009-03-01)
Porous nano and micro crystalline tin oxide films were deposited by RF Magnetron Sputtering and doctor blade techniques, respectively. Electrical resistance and impedance spectroscopy measurements, as a function of temperature ...
PVDF-PAni blend: a free-standing film with variable electrical resistance
(Springer, 2017-05-01)
Films made of a blend of polyaniline (PAni) and a nonpolar polyvinylidene fluoride (PVDF) polymer matrix were obtained by the mechanical mixing of both, with subsequent melting and quenching. Using the current versus voltage ...
