Humidity effects on the electrical properties of hexagonal boron nitride thin films

Ali Soltani, P. Thevenin, H. Bakhtiar, A. Bath

Thin films of hexagonal boron nitride (h-BN) were grown by a plasma enhanced chemical vapour deposition (PECVD) technique. The quality of the films was assessed by infrared spectroscopy, microRaman spectroscopy as a function of annealing temperature and by X-ray photoelectron spectroscopy. The…

Exons, introns and DNA thermodynamics

Enrico Carlon, Mehdi Lejard Malki, Ralf Blossey

The genes of eukaryotes are characterized by protein coding fragments, the exons, interrupted by introns, i.e. stretches of DNA which do not carry any useful information for the protein synthesis. We have analyzed the melting behavior of randomly selected human cDNA sequences obtained from the…

Electrical damage induced by reactive ion-beam etching of lead-zirconate-titanate thin films

Caroline Soyer, Eric Cattan, Denis Remiens

Ion-beam etching of sputtered Pb(Zrx,Ti1-x)O3 (PZT) thin films with x equal to 0.54 grown on Pt/TiOx/SiO2/Si substrates has been performed using pure Ar gas and a varying CHF3/Ar gas mixing ratio. The etch rate dependence on the process parameters (gas composition, current density, and acceleration…

Left-handed propagation media via photonic crystal and metamaterials

T. Decoopman, T. Crepin, M. Perrin, S. Fasquel, A. Marteau, X. Melique, Eric Lheurette, O. Vanbesien, D. Lippens

We review the electromagnetic properties of artificial structures such as photonic band gap materials (Electromagnetic Band Gap at microwaves) and metamaterials with main emphasis on backward (left-handed) propagation media. We consider free space and guiding structures by showing how the…

Resonant Raman scatterring study of Ar⁺ ion-implanted AlGaN

B. Boudart, Y. Guhel, J.C. Pesant, P. Dhamelincourt, M.A. Poisson

160 keV Ar+ ions were homogeneously implanted in AlGaN at room temperature for device isolation purposes. Resonance Raman spectroscopy and DC electrical measurements were used to monitor the structural and electrical changes of the non-annealed and annealed implanted AlGaN samples with a dose…
