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,...

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...

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...
