Presentation / Conference Contribution
Southworth, J. (2011, July). Homogeneous studies of transiting planets. Presented at IAUS 282: From Interacting Binaries to Exoplanets: Essential Modeling Tools, Tatranska Lomnica

The derived physical properties of the known transiting extrasolar planetary systems come from a variety of sources, and are calculated using a range of different methods so are not always directly comparable. I present a catalogue of the physical pr... Read More about Homogeneous studies of transiting planets.

Laser writing of the electronic activity of N- and H-atoms in GaAs (2011)
Journal Article
Martelli, F., Rubini, S., Balakrishnan, N., Patanè, A., Makarovsky, O., Polimeni, A., & Capizzi, M. (2011). Laser writing of the electronic activity of N- and H-atoms in GaAs. Applied Physics Letters, 021105 - 021105. https://doi.org/10.1063/1.3610464

We use a focussed laser beam to control the electronic activity of N- and H-atoms in a dilute nitride Ga(AsN)/GaAs quantum well. Our approach yields submicron resolution in the spatial manipulation of the electronic properties and can provide an alte...

On a class of three-phase checkerboards with unusual effective properties (2011)
Journal Article
(2011). On a class of three-phase checkerboards with unusual effective properties. Comptes Rendus Mécanique, 411-417. https://doi.org/10.1016/j.crme.2011.03.016

We examine the band spectrum, and associated Floquet-Bloch eigensolutions, arising in a class of three-phase periodic checkerboards. On a periodic cell $[-1,1[^2$, the refractive index is defined by $n^2= 1+ g_1(x_1)+g_2(x_2)$ with $g_i(x_i)= r^2\qua...

Theoretical Study of Carbon Clusters in Silicon Carbide Nanowires (2011)
Journal Article
(2011). Theoretical Study of Carbon Clusters in Silicon Carbide Nanowires. Journal of Nanotechnology, 1 - 8. https://doi.org/10.1155/2011/203423

Using first-principles methods we performed a theoretical study of carbon clusters in silicon carbide (SiC) nanowires. We examined small clusters with carbon interstitials and antisites in hydrogen-passivated SiC nanowires growth along the [100] and...

Boron and nitrogen impurities in SiC nanoribbons: anab initioinvestigation (2011)
Journal Article
Abreu Da Silva Morbec. (2011). Boron and nitrogen impurities in SiC nanoribbons: anab initioinvestigation. Journal of Physics: Condensed Matter, 205504 - 205504. https://doi.org/10.1088/0953-8984/23/20/205504

Using ab initio calculations based on density-functional theory we have performed a theoretical investigation of substitutional boron and nitrogen impurities in silicon carbide (SiC) nanoribbons. We have considered hydrogen terminated SiC ribbons wit... Read More about Boron and nitrogen impurities in SiC nanoribbons: anab initioinvestigation.

Requirements for commercial X-ray element-specific imaging technology (2011)
Journal Article
Austin, J. (2011). Requirements for commercial X-ray element-specific imaging technology. Insight - Non-Destructive Testing & Condition Monitoring, 53(3), 127 - 131. https://doi.org/10.1784/insi.2011.53.3.127

Analysis of the composition of material samples nondestructively by means of standard X-ray tube imaging is extremely challenging due to the breadth of the bremsstrahlung spectrum, resulting from mono-energetic electrons striking a thick tungsten tar...
