Geuzaine, C., Bruno, O., V Sabariego, R., & Colignon, D. (2008). High-Frequency Integral Equation Solver for 3-D Wave Scattering Around Convex Obstacles. Proceedings of 6ème Conférence Européenne sur les Méthodes Numériques en Electromagnétisme (NUMELEC2008). Liege, Belgium.
Peer reviewed
We present a numerical method for the computation of wave scattering by convex three-dimensional obstacles, which exhibits a bounded computational complexity for arbitrarily high frequencies. The method is ...
Colignon, D., Kartheuser, E., & Villeret, M. (2000). The effect of electron-phonon interaction in iron-doped III-V cubic semiconductors. Journal of Physics : Condensed Matter, 12(12), 2691-2699.
Peer reviewed (verified by ORBi)
A theoretical study of optical absorption and emission measurements of Fe2+ as a substitutional impurity in InP and GaP is presented. A new interpretation of the low-temperature absorption spectrum is proposed ...
Gérard, J.-C., Dols, V., Colignon, D., Grodent, D., Clarke, J. T., Waite, J. H., & Gladstone, G. R. (1998). FUV spectroscopy of the H_2 emission in the Jovian aurora: model update and results. Bulletin of the American Astronomical Society (pp. 1083).
The Jovian aurora exhibits bright emissions mainly due the bright Lyman-alpha line and to radiation from excited singlet states to the ground electronic state extending from 800 to 1600 Angstroms. Above 1200 ...

Peer reviewed (verified by ORBi)
A theoretical study of the isotopic-mass dependence of the internal transitions of Fe2+ at a cation site in a cubic zinc-blende semiconductor is presented. The model used is based on crystal-field theory and ...

Peer reviewed (verified by ORBi)
Optical-absorption and emission measurements of doubly ionized iron in CdTe, ZnTe, ZnSe and ZnS have been analyzed by means of a vibronic coupling model. The model [1] is based on the crystal-field theory ...

Peer reviewed (verified by ORBi)
The D-5 terms of Fe2+ and Cr2+ in the tetrahedral potential at cation sites in II-VI compounds split into orbital doublet and triplet states. While in Cr2+ the orbital tripler has lower energy than the doublet ...
