Confirmação matemática do efeito Aharonov-Bohm no modelo sem interação com a fronteira do solenóide
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Matemática - PPGMCâmpus São Carlos, 2016-05-30)
We study the Aharonov-Bohm effect model by adding a scalar potential in the initial Hamiltonian. Using known techniques of quantum confinement, we show that under certain conditions of divergence on this potential, the ...
Estudo dos efeitos da orientação do campo magnético sobre a estrutura eletrônica de poços quânticos semicondutores
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2015-03-27)
This work is aimed to theoretically determine, based on the k p method, the energy spectrum
of the minimum of conduction band and the top of valence band, in a quantum well
heterostructure based on gallium arsenide, ...
First principles calculations for vacancies and antisites in PbSe and PbTe: bulk and nanowire.
(Sociedade Brasileira de FísicaÁguas de Lindóia, 2013-05-13)
The energetic stability and the electronic properties of vacancies (VX) and antisites (XY) in PbSe and PbTe are investigated. PbSe and PbTe are narrow band gap semiconductors and have the potential to be used in infrared ...
Raman spectroscopy of nanographites
(Universidade Federal de Minas GeraisUFMG, 2006-09-28)
This work presents the application of the Raman spectroscopy for the study and characterization of nanographite systems. We report the ¯rst detection of nanographite ribbons on a highly oriented pyrolytic graphite substrate ...
