Dielectric Anisotropy in Partially Grain-Oriented Bi2VO5.5 Ceramics
Dielectric Anisotropy Grain-Oriented Bi2VO5.5 Ceramics
2010/12/14
Ceramics obtained from quenching melts of prereacted polycrystalline Bi2V5.5 exhibit grain orientation (~ 55%). Microstructural studies carried out using scanning electron microscopy (SEM) on subseque...
Dependence of the Sheet Resistivity and Current Noise Behaviour of the Grain Size and Volume Fraction of Conducting Material in Thick-Film Resistors Experiments
the Grain Size Conducting Material Thick-Film Resistors Experiments
2010/12/21
Experimental results concerning the dependence of the sheet resistivity and the noise coefficient on the grain size and the volume fraction, respectively, of the metallic-like component in Bi2Ru2O7-ba...
Comment on the Dependence of R□ and Current Noise on Grain Size in Thick Film Resistors (TFR's)
Current Noise Grain Size Thick Film Resistors
2010/12/23
The heterogeneous structure of TFR's results in high resistivities and high current noise. Accepting models of conduction in TFR's, according to which the resistivity is determined by a resistance ind...
Empirical Results Establishing the Thermal Independence of the Grain-Boundary Reflection Coefficient
the Thermal Independence the Grain-Boundary Reflection Coefficient
2011/1/10
Starting from the effective Fuchs–Sondheimer model of electronic conduction in thin polycrystalline films and implementing the asymptotic expressions of conductivity it is shown that the hypothesis of...
