On the doughnut effect and the rainbow proton-silicon interaction potential
(Advanced Ceramics and Applications, 2021)
This work shows how recent experimental results of angular distributions of 2 MeV protons channeled in a 55-nm-thick (001) silicon crystal tilted away from the [001] direction can be explained by the very accurate rainbow ...
Ion channeling implantation induced MgF2 crystal damage through the “eye” of photoluminescence spectroscopy
(27th International Conference on Applied Physics of Condensed Matter : APCOM 2022 : the book of abstracts; June 22 - 24; Strbske Pleso, Slovak Republic, 2023)
Magnesium fluoride (MgF2) single crystal has been widely used as a material for application in optics due to its excellent properties like birefringence, wide range of transparency and low refractive index. As such, MgF2 ...
Angular distributions of ions channeled in the 〈1 0 0〉 Si crystals
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2002)
In this study we analyze the angular distributions of Ne10+ ions channeled in the LT 100 GT Si crystals. The ion energy is 60 MeV and the crystal thickness is varied from 286 to 3435 nm. This thickness range corresponds ...
Application of the crystal rainbow effect as a basis for a nuclear analytical method
(27th International Conference on Applied Physics of Condensed Matter : APCOM 2022 : the book of abstracts; June 22 - 24; Strbske Pleso, Slovak Republic, 2023)
In this work the crystal rainbow effect is described. Its application for determination of the ion-solid interaction potential, which is one of basic problem in ion-solid interaction, is presented. The crystal rainbow ...
Quantum Rainbows in Positron Transmission through Carbon Nanotubes
(Atoms, 2019)
Here we report the results of the theoretical investigation of the transmission of channeled positrons through various short chiral single walled carbon nanotubes (SWCNT). The main question answered by this study is “What ...
Classical patterns in the quantum rainbow channeling of high energy electrons
(Physical Review A, 2021)
We are investigating the quantum dynamics of a well-collimated electron beam transmitting through planar channels of the Si crystal. Electron states were represented by wave packets while the electron beam is treated as ...
Coordinated self-interference of wave packets: a new route towards classicality for structurally stable systems
(Scientific Reports, 2020)
This is a study of proton transmission through planar channels of tungsten, where a proton beam is treated as an ensemble of noninteracting wave packets. For this system, the structural stability manifests in an appearance ...
Raman mapping of 4‐MeV C and Si channeling implantation of 6H‐SiC
(Journal of Raman Spectroscopy, 2019)
A 6H-SiC single crystal implanted in channeling mode by 4-MeV C+3 and Si+3 ions at various doping levels has been examined by scanning electron microscopy (SEM) and micro-Raman spectroscopy in order to study the lattice ...
Influence of the Charge State of Xenon Ions on the Depth Distribution Profile Upon Implantation into Silicon
(Semiconductors, 2019)
Abstract: Experimental depth distributions of the concentration of implanted xenon ions depending on their charge state and irradiation energy are presented. Xenon ions in charge states q = 1–20 and energies in the range ...
On the phase-space catastrophes in dynamics of the quantum particle in an optical lattice potential
(Chaos, 2020)
We have investigated the dynamics of a quantum particle in the optical lattice potential. Initially, the quantum particle was represented by a Gaussian wave packet, located in the center of the well. The corresponding ...
