Thickness dependence of structure and piezoelectric properties at nanoscale of polycrystalline lead zirconate titanate thin films
(2013-05-14)
Lead zirconate titanate Pb(Zr0.50Ti0.50)O3 (PZT) thin films were deposited by a polymeric chemical method on Pt(111)/Ti/SiO2/Si substrates to understand the mechanisms of phase transformations and the effect of film thickness ...
The influence of thermal treatment on the preparation of PNM and PMN-PT thin films
(Elsevier B.V., 2003-03-01)
Ferroelectric thin films belong to a class of materials with great technological importance in optic fibers, micro-electromechanical systems, and microprocessors and computers memories.The (1-x)PbMg1/3Nb2/3O3(x)PbTiO3 ...
The influence of crystallization route on the properties of lanthanum-doped Bi4Ti3O12 thin films prepared from polymeric precursors
(Elsevier B.V., 2004-11-15)
Pure and lanthanum-doped Bi4Ti3O12 thin films were deposited on Pt/Ti/SiO2/Si substrate using a polymeric precursor solution. The spin-coated films were specular and crack-free and crystalline after annealing at 700 degreesC ...
Langmuir and Langmuir-Blodgett (LB) films of tetrapyridyl metalloporphyrins
(Elsevier B.V., 2008-07-15)
We report on the formation of Langmuir films of 5,10,15,20-tetra(4-pyridyl) 21H,23H-porphine,hereafter named tetrapyridyl porphyrins with distinct central ions (2H(+), Zn(2+), Cu(2+), Ni(2+)). The films were characterized ...
The influence of preparation method of OC1OC6-PPV films on the photo-oxidation process
(Elsevier B.V., 2006-10-01)
Poly(p-phenylene vinylene) (PPV) derivatives are well known for their applications in polymer light emitting diodes (PLEDs). PPV derivatives are highly susceptible to photo-oxidation though, which is mainly caused by the ...
Nanostructured hybrid films containing nanophosphor: Fabrication and electronic spectral properties
(Elsevier B.V. Sa, 2012-11-15)
The intensive research of the optical properties of rare-earth ions is due to the high quantum efficiency of their emission, very narrow bands, and excellent fluorescence monochromaticity. The photoluminescence data presented ...
Optical, mechanical and surface properties of amorphous carbonaceous thin films obtained by plasma enhanced chemical vapor deposition and plasma immersion ion implantation and deposition
(2013-09-01)
Diverse amorphous hydrogenated carbon-based films (a-C:H, a-C:H:F, a-C:H:N, a-C:H:Cl and a-C:H:Si:O) were obtained by radiofrequency plasma enhanced chemical vapor deposition (PECVD) and plasma immersion ion implantation ...
Microstructural investigation of the PZT films prepared from the suspension of nanocrystalline powders
(Elsevier B.V., 2004-01-01)
PZT thin films of composition Pb(Zr0.52Ti0.48)O-3 were prepared by a novel method from the suspension of nanocrystalline PZT powders. The powders were obtained by mechanochemical synthesis. Films were deposited on silicon ...
One-dimensional analytical model for oxide thin film growth on Ti metal layers during laser heating in air
(2001-05-15)
This paper presents the theoretical and experimental results for oxide thin film growth on titanium films previously deposited over glass substrate. Ti films of thickness 0.1 μm were heated by Nd:YAG laser pulses in air. ...
Spectroscopy and electrochemical characterization of Langmuir-Blodgett and physical vapor thin films of 29-membered diazocrown ether 1 with two n-octyl substituents
(Elsevier B.V. Sa, 2012-07-01)
UV-vis and FTIR spectroscopy and electrochemistry studies were performed on Langmuir-Blodgett (LB) and on physical vapor deposition (PVD) films of 29-membered diazocrown ether with two n-octyl substituents. FTIR and UV-vis ...
