Investigação teórica sobre possíveis aplicações na eletrônica de nanofios de AlN, GaN e InN: um estudo de primeiros princípios
(Universidade Federal de Santa Maria, 2012-07-30)
Using the formalism of Density Functional Theory with spin polarization and the Generalized
Gradient Approximation for exchange and correlation term, we studied the stability
and electronic properties of substitutional ...
Estudo de primeiros princípios de nanofios em arseneto de índio e fosfeto de índio
(Universidade Federal de Santa Maria, 2011-07-29)
In this work we used the density functional theory to study InAs and InP nanowires
and InAs/InP nanowire heterostructures. Initially we studied the structural, electronic
and mechanical properties of InAs and InP nanowires ...
Estudo computacional da condutividade térmica de nanofios de Si
(Universidade Federal de Santa Maria, 2014-05-15)
In this work the thermal conductivity κ of Si nanowires using molecular dynamics simulations is calculated using the Müller-Plathe method. We show that at 500 K, κ for crystaline Si is 121; 557 W/mK, while for nanowires, ...
Estudo das propriedades estruturais, eletrônicas e termoelétricas de nanofios de PbSe e PbTe
(Universidade Federal de Santa Maria, 2013-04-29)
In this work we study simultaneously the structural, electronic and thermoelectric
properties of PbSe and PbTe nanowires, analyzing the quantum confinement effects, the
dependence with the planar stoichiometry and the ...
Estudo de primeiros princípios de nanofios de inas submetidos a tensões extremas
(Universidade Federal de Santa Maria, 2015-03-30)
The ability to manipulate materials at the atomic scale turn it possible to look
for materials at the nanoscale that can supersede the performance of their bulk counterparts
in specific tasks. Nanowires, due to their ...
