- Designe multifunctional oxides with perovskite architecture (Pb, Sr, La, BI) (Ti, Fe) O3, AP.R
Abstract
Nowadays, Perovskite ferroelectric oxides are multifunctional materials that have been the focus of intense technologic and scientific research. They can even show novel coupling of multiple coexisting states, such as magnetism and superconductivity, or ferroelectricity and ferromagnetism. They can be used to fabricate various devices including nonvolatile ferroelectric random access me...
- Epitaxial growth and characterization of thin films: conducting oxides and ferroelectric prepared by chemical solution deposition, BP.MS
Abstract
At the current stage of technological development is desirable to obtain devices with dimensions (miniaturization) dwindling and can effectively play the role for which they were intended. So apply as ferroelectric thin films has become a challenge and a solution to the technological aspirations so that the properties to be explored should also be included in this configuration. Epitaxi...
- Preparation and characterization of Sr1-xLaxTiO3 thin films as a candidate for electro-optical devices, BP.IC
Abstract
The technological advances driven by the strong development of informatics in recent decades intensified the need to search for new devices, such as in the form of nanostructured thin films like the compact power source, lightweight and, above all, low cost, with a great potential in application as solar cells, transparent conducting oxides, sensors and specially in the current memories...
- Preparation and study of TiO2 nanoparticles doped with Fe processed by hydrothermal synthesis, BP.IC
Abstract
The environmental problems generated by industrial and human activities have increased the need for the development of alternative technologies for the remediation of contaminated aquatic systems. The heterogeneous photocatalysis using titanium dioxide, has been shown effective in this aspect. In order to increase the photocatalyst's efficiency many scientific studies have used the dopi...
