Two Dimensional Honeycomb Materials: Random Fields, Dissipation and Fluctuations
(2017-02-01)
In this paper, we propose a method to describe the many-body problem of electrons in honeycomb materials via the introduction of random fields which are coupled to the electrons and have a Gaussian distribution. From a ...
Relation between Luminescence and Electronic Surface Characteristics in p-type Porous Silicon
(1997)
Measurements of photoluminescence, electronic surface states and effective surface area, at various stages of the anodization process, are presented. The results show a behavior different from that observed on n-type porous Si.
Controle aprimorado para console de jogos eletrônicos
(Universidade Tecnológica Federal do ParanáCampo MouraoBrasilDepartamento Acadêmico de EletrônicaEngenharia EletrônicaUTFPR, 2015-02-13)
With the electronic games evolution, mainly the fighting genre, in many different consoles, it’s visible an increase on the difficulty of the gameplay, which can provide a less pleasurable game for the player. In this ...
The effect of the projectile intra-site Coulomb repulsion in the surface scattering of many-electron ions.
(Elsevier Science, 2003-11)
In this work a theoretical study of the collision of many-electron ions with a surface is performed. The case of largeangle collisions with respect to the surface and projectiles with an open shell is treated. Two important ...
Many-electron model for multiple ionization in atomic collisions
(IOP Publishing, 2007-12)
We have developed a many-electron model for multiple ionization of heavy atoms bombarded by bare ions. It is based on the transport equation for an ion in an inhomogeneous electronic density. Ionization probabilities are ...
Partitioning technique procedure revisited: Application to many-electron systems using the Møller–Plesset Hamiltonian
(2002)
A method to solve the electronic Schrödinger equation based on the modified partitioning procedure (MPP) and here denominated extended MPP (EMPP) is presented. We apply this procedure to molecular systems using the ...
Structural and magnetic changes induced by electron and ion irradiation on HOPG
(2015)
In recent decades, many studies reported magnetism in carbon-based materials. This phenomenon was attributed to structural defects within the sample. Many authors showed an increase of magnetization in HOPG (Highly Oriented ...
Density functional theory and an experimentally-designed energy functional of electron density
(2016-01-01)
We herein demonstrate that capacitance spectroscopy (CS) experimentally allows access to the energy associated with the quantum mechanical ground state of many-electron systems. Priorly, electrochemical capacitance, C[ρ], ...
