Resolving the structure of the striped Ge layer on Ag ( 111 ) : Ag 2 Ge surface alloy with alternate fcc and hcp domains

K. Zhang, D. Sciacca, A. Coati, R. Bernard, Yves Borensztein, Pascale Diener, B. Grandidier, Isabelle Lefebvre, M. Derivaz, C. Pirri, Geoffroy Prévot

Two-dimensional (2D) honeycomb lattices beyond graphene, such as germanene, promise new physical properties such as quantum spin Hall effect. While there have been many claims of growth of germanene, the lack of precise structural characterization of the epitaxial layers synthesized hinders further…

Using saliency detection to improve multi-focus image fusion

Sarra Babahenini, Fella Charif, Foudil Cherif, Abdelmalik Taleb-Ahmed, Y. Ruichek

In this paper, we introduce a novel and efficient algorithm based on saliency detection methods, our main contribution is a new manner to calculate the weight map by normalising the saliency values obtained from the input images, which makes it possible to differentiate the focused and defocused…

Mildly-doped polythiophene with triflates for molecular recognition

Aicha Boujnah, Aimen Boubaker, Adel Kalboussi, Kamal Lmimouni, Sébastien Pecqueur

Organic semiconductors have enough molecular versatility to feature chemo-specific electrical sensitivity to large families of chemical substituents via different intermolecular bonding modes. This study demonstrates that one single conducting polymer can be tuned to either discriminate water-,…

Morphological influence of BiVO4 nanostructures on peroxymonosulfate activation for highly efficient catalytic degradation of rhodamine B

Khawla Missaoui, Rachid Ouertani, Elyes Jbira, Rabah Boukherroub, Brahim Bessaïs

Bismuth vanadate (BiVO4) nanostructured films were prepared and successfully applied for peroxymonosulfate (PMS) activation for the degradation of rhodamine B (RhB) in aqueous solution. The BiVO4 thin films were obtained by thermal reaction between electrodeposited bismuth (Bi) films and vanadium…

Numerical study of high-efficient and high-speed In0.1Ga0.9 N/GaN multiple quantum well photodiodes

Okba Saidani, Souad Tobbeche, El Hadj Dogheche, Bandar Alshehri

This paper presents a numerical simulation study of p-i-n photodiodes based on In0.1Ga0.9 N/GaN multiple quantum wells (MQWs) of 2.5-nm-thick In0.1Ga0.9 N QWs and 12-nm-thick GaN barriers embedded into the intrinsic regions. The device performance is evaluated by investigating both the spectral and…

Organic doped diode rectifier based on parylene-electronic beam lithography process for radio frequency applications

Khaoula Ferchichi, Sébastien Pecqueur, David Guérin, Ramzi Bourguiga, Kamal Lmimouni

We have adapted a "peel-off" process to structure stacked organic semiconductors (conducting polymers or small molecules) and metal layers for diode microfabrication. The fabricated devices are organic diode rectifier in a coplanar waveguide structure. Unlike conventional lithographic…
