Effect of powder milling and dopant addition on the current-voltage characteristics of SnO2-based ceramics
(2001-01-01)
Non-linear electrical properties of SnO2-based ceramics were investigated as a function of powder agglomeration condition and as a function of dopant addition. All doped powders presented a single phase, cassiterite, as ...

Dielectric response of tungsten modified Ba(Ti0.90Zr0.10)O3 ceramics obtained by mixed oxide method
(2010)
The electrical response of Ba(Ti0.90Zr0.10)O3 (BZT) ceramics obtained by the mixed oxide method as a functionof tungsten content was investigated. According to X-ray diffraction analysis the single phase BZT1W (1wt.% W ...
Development of seminconductor nanowire materials for electronic and photonics applications
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2019-12-05)
The thesis is concerned with study of GaAs nanowires fabricated on Si substrate.
The possibility of growing III-V semiconductor materials directly on silicon in the
form of nanowires is an attractive route to the integration ...

Zn(0.97)M(0.03)O (M = Co, Fe, and V) pigments: thermal, structural, and optical characterization
(SPRINGER, 2011)
Zinc oxide is a widely used white inorganic pigment. Transition metal ions are used as chromophores and originate the ceramic pigments group. In this context, ZnO particles doped with Co, Fe, and V were synthesized by the ...
Excitation mechanisms and effects of dopant concentration in Gd2O2S : Tb3+ phosphor
(Elsevier B.V., 2008-07-01)
Gadolinium oxysulfide powders doped with different Tb3+ concentrations were prepared from sulfur vaporization on rare earths' basic carbonate precursors. Single-phase Gd2O2S samples were obtained, with Tb3+ doping up to 9 ...
EPR study of Cu(II) dopant ions in single crystals of bis(L-asparaginato)Zn(II)
(Elsevier, 2006-12)
We report an electron paramagnetic resonance (EPR) study at 33.9 GHz and room temperature of oriented single crystal samples of bis(Lasparaginato) Zn(II) doped with Cu(II). The variation of the spectra with magnetic field ...
