Impact of defects on the electrical properties of BiFeO3 thin films
(Taylor & Francis Ltd, 2020-02-17)
The impact of defects on the electrical properties of bismuth ferrite thin films has been studied. Secondary phases and oxygen vacancies were the main defects considered. Thin films with secondary phases show higher ...
Piezoresponse behavior of niobium doped bismuth ferrite thin films grown by chemical method
(Elsevier B.V. Sa, 2010-03-18)
This paper focuses on the piezoresponse characteristics at room temperature in niobium modified bismuth ferrite thin films (BFN) deposited on Pt/TiO(2)/SiO(2)/Si (1 0 0) substrates by the soft chemical method. The obtained ...
Effect of niobium dopant on fatigue characteristics of BiFeO3 thin films grown on Pt electrodes
(Elsevier B.V. Sa, 2009-06-24)
Pure BiFeO3 (BFO) and Nb-doped (BFN) thin films were fabricated by the soft chemical method. The films were polycrystalline when deposited on Pt/Ti/SiO2/Si substrate and annealed at 500 degrees C for 2 h. X-ray diffraction ...
Thickness-dependent piezoelectric behaviour and dielectric properties of lanthanum modified BiFeO3 thin films
(2011)
Bi0.85La0.15FeO3 (BLFO) thin films were deposited on Pt(111)/Ti/SiO2 /Si substrates by the soft chemical method. Films with thicknesses ranging from 140 to 280 nm were grown on platinum coated silicon substrates at 500°C ...
Processing of BiFeO3 thin films to control their dielectric response
(Taylor & Francis Ltd, 2020-05-18)
BiFeO3 (BFO) thin films were studied to control their oxygen-related processing parameters in order to obtain specific electrical characteristics in terms of conductivity and dielectric relaxation. BFO thin films prepared ...
U and Th thin film neutron dosimetry for fission-track dating: Application to the age standard Moldavite
(2005-12-01)
Neutron dosimetry based on U and Th thin films was used for fission-track dating of the age standard Moldavite, the central European tektite, from the Middle Miocene deposit of Jankov (southern Bohemia, Czech Republic). ...
A new polymeric thin film by using electropolymerization: thin film of poly(phenazine-salen) obtained from 2,2'-[1,2-ethanediylbis(nitrilomethylidyne)] -bis[4-amino-phenol]
(2020-09-15)
In the last years, the study of the formation of a polymer containing multidentate Schiff-base ligand as subunits has been performed. In general, the electropolymerization occurs through the interaction between the phenyl ...
Processing and structural properties of random oriented lead lanthanum zirconate titanate thin films
(Elsevier B.V., 2015-01-01)
Polycrystalline lead lanthanum zirconate titanate (PLZT) thin films have been prepared by a polymeric chemical route to understand the mechanisms of phase transformations and map the microstructure and elastic properties ...
Effect of pressure-assisted thermal annealing on the optical properties of ZnO thin films
(2012-12-21)
ZnO thin films were prepared by the polymeric precursor method. The films were deposited on silicon substrates using the spin-coating technique, and were annealed at 330°C for 32h under pressure-assisted thermal annealing ...
