Performance of the structure AlxGa1-xAs1-yNy/Ge for solar cell applications

Wafa Bellil, Abdelkader Aissat, Jean-Pierre Vilcot

The aim of this modeling and simulation is to study the influence of the incorporation of nitrogen (N) and aluminum (Al) on the optoelectronic properties of the structure AlxGa1-xAs1-yNy/Ge, and then choose the right combination (N, Al) which gives us a better conversational efficiency of the...

While nonstoichiometric binary III-V compounds are known to contain group-V antisites, the growth of ternary alloys consisting of two group-V elements might give additional degrees of freedom in the chemical nature of these antisites. Using cross-sectional scanning tunneling microscopy (STM), we...

Enhanced antibacterial activity of carbon dots functionalized with ampicillin combined with visible light triggered photodynamic effects

Roxana Jijie, Alexandre Barras, Julie Bouckaert, Nicoleta Dumitrascu, Sabine Szunerits, Rabah Boukherroub

In the last years, carbon-based nanomaterials have attracted considerable attention in a wide range of fields, particularly in biomedicine, owing to their remarkable photo-physical and chemical properties. In this study, we demonstrate that amine-terminated carbon dots (CDs-NH2) functionalized with...

On the occurrence of size effects in the calculation of thermal conductivity by first-principles molecular dynamics: The case of glassy GeTe4

Évelyne Martin, Pier Luca Palla, Fabrizio Cleri, Assil Bouzid, Guido Ori, Sébastien Le Roux, Mauro Boero, Carlo Massobrio

The thermal conductivity of a glass can be obtained by first-principles molecular dynamics provided we exploit a methodology that has been termed the approach-to-equilibrium molecular dynamics (AEMD) [1] [2, Chap. 8]. In the present work, we investigate the occurrence of size effects by comparing...

Automatic modulation classification for D-STBC cooperative relaying networks

Hakim Tayakout, Iyad Dayoub, Khalida Ghanem, Hicham Bousbia-Salah

Automatic modulation classification (AMC) has been used as a crucial component to improve the overall performance in cognitive radio system, thereby allowing any user to promote secure and reliable communication. In this letter, we propose a semi-blind AMC approach based on a simplified distributed...

Highly confined Love waves modes by defect states in a holey SiO2 /quartz phononic crystal

Yuxin Liu, Abdelkrim Talbi, Philippe Pernod, Olivier Bou Matar

Highly confined Love modes are demonstrated in a phononic crystal based on a square array of etched holes in SiO 2 deposited on the ST-cut quartz. An optimal choice of the geometrical parameters contributes to a wide stop-band for shear waves' modes. The introduction of a defect by removing...

Enhanced photovoltaic performance of inverted polymer solar cells through atomic layer deposited $Al_{2}$$O_{3}$ passivation of ZnO-nanoparticle buffer layer

Bin Wei, Zhenyu Tang, Shuanglong Wang, Cunping Qin, Chunya Li, D Ding, Yulai Gao, X. Portier, F. Gourbilleau, D. Stievenard, Tao Xu

In this work, an atomic layer deposited (ALD) $Al_{2}$$O_{3}$ ultrathin layer was introduced to passivate the ZnO-nanoparticle (NP) buffer layer of inverted polymer solar cells (PSCs) based on P3HT:PCBM. The surface morphology of the ZnO-NP/$Al_{2}$$O_{3}$ interface was systematically analyzed by...

Structure électronique et propriétés de réseaux cohérents de nanocristaux semi-conducteurs, Electronic structure and properties of coherent superlattices of semiconductor nanocrystals

Athmane Tadjine

La nanostructuration de matériaux semi-conducteurs permet de modifier le comportement des porteurs de charge. Ces modifications sont causées par les effets de confinement quantique. Dans cette thèse, nous étudions par des approches théoriques (numériques et analytiques) les propriétés de réseaux..., Semiconductor nanostructuration methods are a new route leading to the tuning of charge carriers behavior. This tuning is a direct consequence of the quantum confinement effect. In this thesis, we study using numerical and analytical approaches the properties of coherent superlattices of...
