Efeitos de spin em diodos de tunelamento ressonante tipo-p 

Galeti, Helder Vinicius Avanço (Universidade Federal de São Carlos, 2012-03-27)
In this work, we have investigated the spin effects in p-i-p GaAs/AlAs resonant tunneling diodes under magnetic field parallel to the tunnel current. The spin-dependent tunneling of carriers was studied by analyzing the ...

Propriedades microestruturais e magnéticas de policristais de V2O5, CoV2O6 e Co3O4 sintetizadas por método Pechini 

Dreifus, Driele Von (Universidade Federal de São Carlos, 2014-11-27)
In this work we performed an extensive research about the magnetic properties of three materials, vanadium pentoxide (V2O5), cobalt tetraoxide (Co3O4) and cobalt vanadate II (CoV2O6). All the three oxides were synthesized ...

Manipulação de spin em diodos de tunelamento ressonante não-magnéticos tipo-n 

Santos, Lara Fernandes dos (Universidade Federal de São Carlos, 2010-04-01)
The aim of this work was to study the spin effects in non-magnetic asymmetric n-type resonant tunneling diodes (RTD). For this purpose, we have used transport and polarization resolved magneto-photoluminescence measurement ...

Caracterização das propriedades ópticas e de spin de poços quânticos de InGaAsN/GaAs 

Ballottin, Mariana Victória (Universidade Federal de São Carlos, 2015-03-30)
In this work, it was investigated the optical and magneto-optical properties of In- GaAsN/GaAs and InGaAs/GaAs double quantum wells. It was performed a systematic experimental study of photoluminescence (PL) as a function ...

Estudo da alumina anódica porosa como sensor para diferentes gases 

Guerreiro, Haroldo de Almeida (Universidade Federal de São Carlos, 2013-04-18)
In this project we studied the porous anodic alumina as a possible application in gas sensors with high sensitivity. Initially we seek a configuration of anodic porous alumina (PA) and the type of gas or vapor in which ...

Propriedades espectroscópicas da ação antimicrobiana do peptídeo polycerradin 

Nascimento, Isabella Sampaio do (Universidade Federal de São Carlos, 2015-02-03)
The spectroscopy is a technique based on light-matter interaction, which provides information about the composition and structure of molecules. For this reason, it is used in various fields of science, including the biology. ...

Eletrocerâmicas multifuncionais ecologicamente corretas baseadas em (Bi0,5Na0,5)TiO3: a influência da dopagem doadora sobre suas propriedades físicas 

Diaz, Julio Cesar Camilo Albornoz (Universidade Federal de São Carlos, 2018-08-30)
In the current context of research that points to the development of ecologically correct materials highlights the fact that a single family of materials can not be obtained capable of mimicking all the properties of PZTs ...

Caracterização ótica de poços quânticos de GaMnAs 

Holgado, Danny Pilar Araucano (Universidade Federal de São Carlos, 2007-09-12)
In this work, we have studied GaAs/AlAs/Ga1-xMnxAs quantum wells (QWs) with low Mn concentration ( 0 < x < 0,2%). The samples were grown by Molecular Beam Epitaxy (MBE) in high temperature (450 C). The growth conditions ...

Controle da emissão visível de nanopartículas baseadas em óxido de zinco 

Curcio, Ana Laura (Universidade Federal de São Carlos, 2021-02-25)
We present a study of the synthesis processes and of the structural, vibrational and optical properties of Zn1-xCdxO nanostructured system. The Zn1-xCdxO samples were synthesized using mechanosynthesis method, in the ...
