Transporte eletrônico por estados topológicos em grafeno bicamada dobrado: uma plataforma para a valetrônica
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE FÍSICAPrograma de Pós-Graduação em FísicaUFMG, 2019-07-11)
Valetronics is an emergent field on electronics that manipulates the valley number, a degree
of freedom similar to the electron spin, to develop faster and more efficient devices with
low power consumption. The development ...
Transport phenomena in nontrivial topological materials
(2023)
In this Ph.D. thesis, we present our work related to electronic quantum transport in materials with nontrivial topology. The fundamental objectives of our work were as follows: Firstly, to study ballistic transport in a ...
Multi-length and time scale thermal transport using the lattice Boltzmann method with application to electronics cooling
(PERGAMON-ELSEVIER SCIENCE LTD, 2006)
The lattice Boltzmann method (LBM) is used to investigate one-dimensional, multi-length and -time scale transient heat conduction in crystalline semiconductor solids, in which sub-continuum effects are important. The ...

(2018)
The sediment transport driven by a river or a channel flow is a phenomenon that operates at different scales. At the smallest scales, the coherent structures of the turbulent boundary layer are the mechanisms that govern ...
Influence of phonon dispersion on transient thermal response of silicon-on-insulator transistors under self-heating conditions
(ASME, 2007)
Lattice Boltzmann method (LBM) simulations of phonon transport are performed in one-dimensional (ID) and 2D computational models of a silicon-on- insulator transistor, in order to investigate its transient thermal response ...
Disorder-free weak dynamic localization in deformable lattices
(Institute of Physics Publishing, 2018)
© 2018 IOP Publishing Ltd.We study the electron transport in a deformable lattice modeled in the semiclassical approximation as a discrete nonlinear elastic chain where acoustic phonons are in thermal equilibrium at ...
Universal zero-bias conductance through a quantum wire side-coupled to a quantum dot
(2009-12-16)
A numerical renormalization-group study of the conductance through a quantum wire containing noninteracting electrons side-coupled to a quantum dot is reported. The temperature and the dot-energy dependence of the conductance ...
The diffusive transport of waves in a periodic waveguide
(AMER PHYSICAL SOC, 2012-01-19)
We study the propagation of waves in quasi-one-dimensional finite periodic systems whose classical (ray) dynamics is diffusive. By considering a random matrix model for a chain of L identical chaotic cavities, we show that ...
