Vidros: sólidos ou líquidos? Uma análise via simulação computacional
(Universidade Federal de São Carlos, 2019-10-10)
For many centuries there were different definitions of what glass would be, this discussion
persists to current days. Is glass a solid or liquid material? In this work, we answer this question
through computational ...
Tunelamento ressonante de férmions massivos de Dirac em sistemas de simples e dupla barreiras em monocamada de grafeno
(Universidade Federal de São Carlos, 2015-04-29)
Nowadays, several efforts have been made by research groups around the physical
properties of the graphene in view of the possible technological applications of their
unique structural and electronic properties. The ...
Investigação das propriedades magnéticas de amostras de IrO2 e Co:IrO2 sintetizadas via método de Pechini
(Universidade Federal de São Carlos, 2010-08-31)
In this work the magnetic properties of iridium oxide synthesized via Pechini s method and doped with different concentrations of cobalt were studied. The proposal was to investigate the possibility of applying it as a ...
Multiferróicos monofásicos a base de Pb(Fe2/3W1/3)O3-PbTiO3: acoplamento magnetoelétrico intrínseco
(Universidade Federal de São Carlos, 2010-11-25)
Multiferroic ceramic solid solutions between the ferroelectric relaxor Pb(Fe2/3W1/3)O3 (PFW) and normal ferroelectric PbTiO3 (PT) [PFW-PT] has been synthesized by a modified B-site precursor method and characterized by ...
Efeitos eletrônicos, elásticos e estruturais em sistemas semicondutores nanoscópicos
(Universidade Federal de São Carlos, 2012-02-16)
The present work aims the study of electronic, elastic and structural properties of a whole class of nanoscopic semiconductors systems, which include quasi-two-dimensional, one-dimensional and zero-dimensional confined ...
Propriedades óticas e de transporte em heteroestruturas semicondutoras contendo GaMnAs
(Universidade Federal de São Carlos, 2011-10-14)
In this work, we have investigated Ga1-xMnxAs/GaAs/AlAs quantum wells (QWs) with low Mn concentration (x < 0.1%) grown by Molecular Beam Epitaxy at substrate temperatures of 400 and 450°C. We have investigated the time-resolved ...
