• Abstract

  Collective behavior of interacting electrons in solids usually leads to the emergence of several complex phenomena in condensed matter such as superconductivity, magnetoresistance, thermoelectricity, complex magnetic ordering, multiferroic properties, metal-insulator transitions, non-Fermi-Liquid behavior (NFL), manifestation of topologically protected egde and/or surface states, etc. All…

• Abstract

  A significant improvement in quality of life of mankind in recent times has been achieved through the development of new materials in various areas of science. The unimaginable technological advances of recent decades has allowed engineering to improve the preparation and characterization of new nanostructured and massive materials, with the concomitant production of new electronic, magne…

  Study and development of advanced novel materials: electronic, magnetic and nanostructured: an interdisciplinary approach, AP.TEM

• Abstract

  In this project we propose to intensify even more the study of the electronic, structural, magnetic, transport and thermodynamics properties of highly correlated materials under the extreme condition of high magnetic fields (d 14 T), low temperatures (e 50 mK) and high pressures (d 30 kbars) in metals, superconductors, semiconductors, semimetals, diluted magnetic semiconductors, ceramic o…

• Abstract

  This Project aims to prepare nanostructures and nanomaterials via chemical synthesis (bottom-up) e physical method of Laser Ablation (LA) (top-down). The nanoparticles will be studied by optical, microwave, radio frequency and magnetization methods.

  Magnetic properties of confined nanostructures: metallic and insulating rare-earth doped nanoparticles prepared by Laser Ablation and Chemical Syntheses., BP.PD

• Abstract

  This project has two lines of basic research. The first proposes the investigation of structural, thermodynamic and electronic properties of nanostructured systems. In particular, two types of nanoparticles (NPs) will be studied: i) Simple metal NPs using noble and transition metals type Au, Ag, Pd, Pt, Cu Al with diluted magnetic impurities (mainly rare earths) and ii) try to obtain inte…

  Study of the physical properties of nanostructured materials and fundamental interactions in bulk systems, BP.PD

• Abstract

  The observed upconversion (UC) phenomena in rare earths doped nanoparticles (NPs) has been recently a subject of intensive studies due to the potential applications in solar energy, lasers, biosensors and bioimagens. However, the optical efficiency of the UC is not enough to guarantee a good performance for most of the technological applications. This have motivated theoretical and experi…

• Abstract

  The research will be focused on the study of the optical effect of Upconversion (UC) on nanoparticles doped with rare-earths. In these materials, the successive absorption of two or more low energy photons (infrared) stimulate the emission of higher energy photons (visible). Depending on the composition (doping with rare-earth), different emission lines in the visible spectrum can be stim…
