Simulação do pico de superfície de Al e Si
(2004) [Dissertation]Espalhamento de íon de energia média (MEIS), em conjunto com as técnicas de sombreamento e bloqueio, representa um poderoso método para a determinação de parâmetros estruturais e vibracionais de superfícies cristalinas. ... -
Theoretical and experimental study of energy loss of Li ions in Zn
(2008) [Journal article]We have performed a combined theoretical and experimental study of the energy loss of Li ions in Zn, on a wide range of energies, together with comparative studies for H and He ions on the same target. By using Zn films ... -
Trajectory dependence of electronic energy-loss straggling at keV ion energies
(2023) [Journal article]We have measured the electronic energy-loss straggling of protons, helium, boron, and silicon ions in silicon using a transmission time-of-flight approach. Ions with velocities between 0.25 and 1.6 times the Bohr velocity ... -
Utilização de técnicas de microfeixe de íons energéticos para caracterização morfológica e elementar de amostras poliméricas e tecidos biológicos
(2014) [Thesis]As técnicas baseadas em microfeixe de íons energéticos possuem aplicações em diferentes áreas de conhecimento, tais como materiais, biologia, neurociência, ciências ambientais, entre outros. A microssonda iônica também ... -
Vanishing influence of the band gap on the charge exchange of slow highly charged ions in freestanding single-layer MoS2
(2020) [Journal article]Charge exchange and kinetic energy loss of slow highly charged xenon ions transmitted through freestanding monolayer MoS2 are studied. Two distinct exit charge state distributions, characterized by high and low charge ... -
Vicinage effect in the energy loss of H2 dimers : experiment and calculations based on time-dependent density-functional theory
(2017) [Journal article]We present a combined theoretical and experimental study of the energy loss of H2 + molecular ions interacting with thin oxide and carbon films.As a result of quantum mechanical interference of the target electrons, the ...
