Interface mixing of Fe/Si bilayers by noble-gas ions: Are there effects of the ionic charge state?
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2007)
Charge-state equilibration of ions moving in matter occurs within femtoseconds and when penetrating nanometer depths. Ion-beam mixing in bilayers, tens of nm thick, should therefore not depend on the charge state of the ...
Stability of nano-scaled Ta/Ti multilayers upon argon ion irradiation
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2011)
The effects of argon ion irradiation on structural changes in Ta/Ti multilayers deposited on Si wafers were investigated. The starting structures consisted of sputter deposited 10 alternate Ta (similar to 23 nm) and Ti ...
Ion beam modification of structural and electrical properties of TiN thin films
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2008)
A study of ion beam modification of structural and electrical properties of TiN thin films is presented. The layers were deposited by reactive ion sputtering on (100) Si and glass slide substrates to a thickness of similar ...
Ion implantation induced structural changes in reactively sputtered Cr-N layers on Si substrates
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2007)
This paper presents a study of the structure and composition of reactively sputtered Cr-N layers as a function of deposition parameters, and the effects of ion implantation on these structures. The layers were deposited ...
Interactions of slowly moving charges with graphene: The role of substrate phonons
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2012)
We study dynamic polarization of single-layer graphene lying on a strongly polar substrate, such as SiC, induced by an external charged particle that moves slowly parallel to graphene. Calculations of the total electrostatic ...
The evolution of hydrogen from proton irradiated glassy carbon
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2011)
Glassy carbon was irradiated with 15 key H(+) ion beam. It was observed that the implanted hydrogen is unstable in material and evolves as H, H(2) and H(2)O. Post-irradiation evolution of H, H(2) and H(2)O from proton ...
Boron ion irradiation induced structural and surface modification of glassy carbon
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2013)
The incorporation of boron into glassy carbon was achieved by irradiating two different types of targets: glassy carbon polymer precursor and carbonized glassy carbon. Targets were irradiated with a 45 keV B3+ ion beam in ...
Effect of illumination on the superconducting transition temperature T-c in YBa2Cu3O6+x
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2012)
In the present study, we have employed two dimensional ASYNNNI model and the numerical Monte Carlo simulations to investigate the effect of visible light or ultraviolet radiation on the doping p of the superconducting CuO2 ...
Study on the photo-induced oxygen reordering in YBa2Cu3O6+x
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2012)
Effect of the long term illumination of the YBa2Cu3O6+x with visible light or ultraviolet irradiation on its superconducting properties was studied in the frame of a simple theoretical model, which assumes that photodoping ...
