Behaviour of a nanometric SnO2 powder under swift heavy-ion irradiation: From sputtering to splitting

Autor: Fabrice Gourbilleau, Ch. Dufour, B. Domengès, E. Paumier, A. Berthelot, S. Hémon

Publikováno v: Philosophical Magazine A. 80:2257-2281

Tin oxide nanometric powders have been irradiated with several swift heavy ions (Ar, Cd, Ta, Pb and U) and observed by transmission electron microscopy (TEM) and high-resolution electron microscopy (HREM). Except for Ar ions, cylindrical tracks are v

Publikováno v: Journal of Physics: Condensed Matter. 12:5011-5020

Single crystal films of Gd and Nd were grown by MBE techniques using the LaMBE facility in Oxford. The thickness of the layers was 5000 Angstrom and the mosaic spread about 0.2-0.3 degrees. Some of the layers were hydrogenated by KTH in Stockholm to

Structural transformation in two yttrium oxide powders irradiated with swift molybdenum ions

Autor: Ch. Dufour, S. Hémon, S. Bégin-Collin, Fabrice Gourbilleau, A. Berthelot, E. Paumier

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. :339-344

Swift molybdenum ions induce a structural transformation in Y 2 O 3 powders: the normal cubic phase is changed into the monoclinic phase. In this paper, it is shown that the initial crystallite size distribution in the grains has an influence on the

A nanometric powder of tin oxide (SnO2) has been irradiated with lead ions. The same grains have been observed by Transmission Electron Microscopy (TEM) before and after irradiation at a fluence of 5×1012 Pb cm−2. The shape of largest grains stron

Influence of the grain size: yttrium oxide irradiated with swift heavy ions

Autor: Eric Dooryhee, E. Paumier, Fabrice Gourbilleau, S. Bégin-Colin, Ch. Dufour, S. Hémon

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. 146:443-448

Our aim is to know whether the irradiation effects depend or not on the size of the crystallized domains in the target. Three different targets of yttrium oxide (a single crystal, a sintered sample and a powder) have been irradiated with lead ions, w

TEM study of irradiation effects on tin oxide nanopowder

Autor: Fabrice Gourbilleau, Ch. Dufour, S. Hémon, Eric Dooryhee, E. Paumier, A. Rouanet

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. 122:526-529

The effects of swift heavy ions in bulk materials have now long been studied and some models — such as the thermal spike — have been developed in order to explain the observed phenomena. Nevertheless, some questions remain debatable, among which
