Scale effects induced by imperfect interfaces in nanomaterials transport properties

Fabio Pavanello, F. Manca, Pier Luca Palla, Evelyne Lampin, Fabrizio Cleri, Stefano Giordano

One of the crucial factors governing the physical properties of nanomaterials is the complex behavior of the interfaces[1]. While at the macroscopic level their specific role is usually neglected, in nanostructured systems the properties of the contact between phases have to be carefully defined.…

Hypersonic band gap in an AlN-TiN bilayer phononic crystal slab

S. Hemon, Abdellatif Akjouj, A. Soltani, Yan Pennec, Y. El Hassouani, Abdelkrim Talbi, V. Mortet, Bahram Djafari-Rouhani

We show both theoretically and experimentally the existence of a complete band gap in a phononic crystal (PnC) constituted by periodical air holes drilled in a solid bi-layer slab. The composite slab is formed with an aluminum nitride (AlN) layer deposited on a titanium nitride (TiN) thin metallic…

Enhanced efficiency by the effect of strain on the structure of a solar cell

Abdelkader Aissat, Rachid Bestam, M. El Bey, Jean-Pierre Vilcot

This paper is expected at the study of Ga1-xInxP/GaAs based solar cell. The effects of indium concentration, lattice parameter mismatch and thickness of the SiO2 insulating layer on the characteristics and efficiency of the Ga1-xInxP/GaAs structure were investigated. We noticed that for higher…

Dispersion characteristic of ultrathin terahertz planar lenses based on metasurface

Dan Hu, Gabriel Moreno, Xinke Wang, Jingwen He, Abdallah Chahadih, Zhenwei Xie, Bo Wang, Tahsin Akalin, Yan Zhang

Terahertz (THz) radiation has attached a lot of attention due to its potential applications. The smart optical components will greatly boost the application of the THz technology. Ultrathin planar lenses which can greatly reduce the thickness of the components are designed and fabricated in the THz…

Improved wet chemical transfer process to obtain clean high quality graphene

Geetanjali Deokar, Jean-Louis Codron, Emmanuelle Pichonat, Xavier Wallart, Henri Happy, Dominique Vignaud

Graphene growth on metal substrates (Cu, Ni etc.) by catalyzed chemical vapor deposition (CVD) is a highly suitable method for large scale production [1,2]. However, graphene based electronic devices full realization requires a clean and reproducible graphene transfer on non-conducting substrates,…
