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.…

Optical and microstructural properties into nanoporous GaN films grown on sapphire by metal organic chemical vapor deposition

Bandar Alshehri, S.-M. Lee, J.-H. Kang, Karim Dogheche, S.-H. Gong, S.-W. Ryu, E. Dumont, Y.-H. Cho, El Hadj Dogheche

Gallium Nitride (GaN) thin films have been prepared on sapphire by metal organic chemical vapor deposition (MOCVD) technique and a chemical etching method using KOH is used to develop nanoporous structures [1]. We present comparative investigations of porous and nonporous GaN layers. While the…

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…

Measurement techniques for RF nanoelectronic devices : new equipment to overcome the problems of impedance and scale mismatch

Henri Happy, Kamel Haddadi, Didier Theron, Tuami Lasri, Gilles Dambrine

Scaling of electronic device dimensions into the nanoscale regime has been at the basis of the semiconductor industry for several decades. Traditional materials have been pushed to their limits, which means that entirely new materials and new device structures are now required. The development of…

Effect of thickness and deposition rate on the structural and magnetic properties of evaporated Fe/Al thin films

M. Mebarki, A. Layadi, L. Kerkache, A. Benabbas, Nicolas Tiercelin, Vladimir Preobrazhensky, Philippe Pernod

We report experimental results on the structural and magnetic properties of Fe thin films deposited by thermal evaporation onto polycrystalline Al substrates. The effect of thickness t (in the 76 to 431 nm range) and deposition rate are investigated. The texture, the strain, and the grain size…

Influence of processing gases on the properties of cold atmospheric plasma SiOxCy coatings

H. Hamze, Maude Jimenez, D. Deresmes, Arnaud Beaurain, Nicolas Nuns, Michel Traisnel

Thin layers of SiOxCy (y = 4−x and 3 ≤ x ≤ 4) were applied using a cold atmospheric plasma torch on glass substrates. The aim was to investigate using Atomic Force Microscopy (AFM), X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (Tof-Sims) the influence of…
