Propriedades eletrônicas e espectroscópicas de aglomerados de moléculas interestelares
(Universidade Federal de São Carlos, 2013-08-29)
The interstellar médium (ISM) is a gigantic reservoir of atoms and molecules of different shapes and sizes. In general, they are concentrated in enormously big regions in space known as interstellar cloud. There exist huge ...
Platforms based on semiconductors for application in quantum computing
(Universidade Federal de São Carlos, 2023-06-02)
This thesis is composed of three parts. In the first part, a study of transport in semiconductor nanowires is carried out, in which the multichannel scattering occurs in a certain finite region, providing a reentrance in ...
The memristive response in solids
(Universidade Federal de São Carlos, 2023-08-07)
In this Master Thesis, we have investigated basic ingredients of the theory of solid state
transport, namely the Drude like conductivity and the activation of nonequilibrium charge
carriers subjected to a relaxation time, ...
Theoretical and experimental investigation on the visible-light controlled functional properties in charged domain wall ferroelectrics
(Universidade Federal de São Carlos, 2023-04-13)
Optical control of ferroelectric properties have been attracted a growing interest as an
alternative to the conventional control by applied electric fields. However, the major
drawback for achieving an effective reversible ...
Relaxação de spin em nanoestruturas semicondutoras 0 e 2D
(Universidade Federal de São Carlos, 2023-03-01)
This thesis contains a compilation of the work developed and is divided into
three main parts. The first part describes the homogeneous and inhomogeneous
decoherence mechanisms of excitons in GaAs/AlGaAs quantum wells. ...
Electromigration of multiterminal transport bridges
(Universidade Federal de São Carlos, 2023-03-09)
With the continued miniaturization of integrated circuits (ICs), the case of metallic tracks subjected to stress caused by transport currents has become a matter of increasing concern, as it puts at risk the reliability ...
Estudos in sı́lico de proteı́nas alostéricas e sua interação com ligantes
(Universidade Federal de São Carlos, 2023-02-24)
Allosteric proteins are extremely important for the regulation of several functions in
the organism, such as the transport of molecules through the blood and cell membranes,
as well as the phosphorylation of other proteins. ...
Influência dos defeitos nas funcionalidades elétricas de ZnO, AgO e polianilina
(Universidade Federal de São Carlos, 2023-03-03)
The optical and electrical properties in a semiconductor can be modeled by structural defects. In this thesis, we study the influence of defects on the optical and electronic properties of organic and inorganic semiconductors ...
Magnetic fields as a tool to control superconducting devices
(Universidade Federal de São Carlos, 2023-10-16)
The quantum nature and dissipation-free flow of electric currents in superconducting materials have taken a central role as technological developments push forward the necessity of new methods for processing and dealing ...
Modelos de branas em (5+1) dimensões e o espectro dos leptóns carregados
(Universidade Federal de São Carlos, 2023-10-27)
This manuscript is concerned with a mechanism for explaining the mass spectrum of
the charged leptons within (5 + 1)-dimensional braneworlds. As a preliminary objective,
new two co-dimensional thick braneworlds ought to ...
