Quantum primary rainbows in transmission of positrons through very short carbon nanotubes
(Elsevier, 2016)
This paper is devoted to a quantum mechanical consideration of the transmission of positrons of a kinetic energy of 1 MeV through very short (11, 9) single-wall chiral carbon nanotubes. The nanotube lengths are between 50 ...
Effective quantum dynamics in a weakly anharmonic interaction in the vicinity of a focusing point
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2017)
We describe here the dynamic behaviors of a quantum ensemble of particles in a one-dimensional anharmonic potential well and of the corresponding classical ensemble in the vicinity of a focusing point. The anharmonicity ...
Rainbow channeling of protons in very short carbon nanotubes with aligned Stone-Wales defects
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2016)
In this paper proton channeling through armchair single-walled-carbon-nanotubes (SWCNTs) with aligned Stone-Wales defects has been investigated. The energy of the proton beam was 1 GeV, while the lengths of the SWCNTs have ...
Proton-silicon interaction potential extracted from high-resolution measurements of crystal rainbows
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2015)
This study provides a way to produce very accurate ion atom interaction potentials. We present the high-resolution measurements of angular distributions of protons of energies between 2.0 and 0.7 MeV channeled in a 55 nm ...
Investigation of deep implanted carbon and oxygen channeling profiles in [110] silicon, using d-NRA and SEM
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2014)
Ion implantation is one of the most important techniques used in the silicon-based semiconductor industry. Using the ion axial channeling effect, which occurs when an ion beam is oriented along a crystallographic axis, it ...
EBS/C proton spectra from a virgin diamond crystal
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2016)
In the present work, elastic backscattering channeling spectra, EBS/C, of protons in a (100) diamond crystal were experimentally and theoretically studied via a new computer simulation code. Proton incident energies for ...
Depth profiling of high energy nitrogen ions implanted in the (100), (110) and randomly oriented silicon crystals
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2012)
This work reports on the experimentally obtained depth profiles of 4 MeV N-14(2+) ions implanted in the (100), (110) and randomly oriented silicon crystals. The ion fluence was 10(17) particles/cm(2), The nitrogen depth ...
Superfocusing and zero-degree focusing in planar channeling of protons in a thin silicon crystal
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2019)
This is a theoretical study of the superfocusing and zero-degree focusing effects appearing in channeling of protons of energy of 2 MeV in the {1 1 0} channel of a thin silicon crystal. We prove that the ultimate origin ...
The forward rainbow scattering of low energy protons by a graphene sheet
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2018)
This article studies the rainbow scattering of 5-key protons by the single sheet of free-standing graphene and its possible use as a tool for investigation of the ion-graphene interaction. The proton-graphene interaction ...
Superfocusing of channeled protons and crystal rainbows
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2009)
This study is devoted to the effect of superfocusing of protons having the energy of 2 MeV in a LT 1 0 0 GT channel of a Si crystal. The analysis is performed by the theory of crystal rainbows. We analyze the superfocusing ...
