Journal ArticleDOI
An empirical potential for the calculation of the atomic structure of extended defects in wurtzite GaN
TL;DR: In this article, the Stillinger-Weber potential has been parametrized for GaN with bond-type dependent parameters to allow efficient atomic simulations of large systems containing wrong, dangling and extra bonds.
Journal ArticleDOI
Formation mechanism and relative stability of the { 112 ¯ 0 } stacking fault atomic configurations in wurtzite (Al,Ga,In) nitrides
P. Ruterana,B. Barbaray,A. Béré,Philippe Vermaut,A. Hairie,E. Paumier,Gerard Nouet,Arnel Salvador,A. Botchkarev,Hadis Morkoç +9 more
TL;DR: In this paper, a modified Stillinger-Weber potential was used in order to investigate the relative stability of the two atomic configurations which have comparable energy in wurtzite (Ga,Al,In)N.
Journal ArticleDOI
Phase transformation induced in pure zirconia by high energy heavy ion irradiation
TL;DR: In this paper, X-ray diffraction and complementary Raman spectroscopy analyses revealed two main features of monoclinic zirconia: 1) the evolution of the amount of the tetragonal phase with the ion fluence exhibits a sigmoidal shape suggesting a mechanism for phase transformation which very likely needs two ion impacts.
Journal ArticleDOI
Atomic and cluster ion bombardment in the electronic stopping power regime: A thermal spike description
TL;DR: In this paper, the thermal spike model is developed using a numerical solution of two coupled equations describing the energy diffusion on the electrons and on the lattice atoms respectively and their coupling.
Journal ArticleDOI
Phase transformation of polycrystalline zirconia induced by swift heavy ion irradiation
C. Gibert-Mougel,F. Couvreur,Jean-Marc Costantini,S. Bouffard,F. Levesque,S. Hémon,E. Paumier,Ch. Dufour +7 more
TL;DR: In this article, room-temperature X-ray diffraction (XRD) and micro-Raman spectroscopy measurements show consistently that a phase transition to the tetragonal form (β-ZrO 2 ) occurs for 170 MeV 84 Kr ion irradiation above an electronic stopping power value around 15 MeV μm −1.
