Electromagnetic Modeling in Near-Field Scanning Microwave Microscopy Highlighting Limitations in Spatial and Electrical Resolutions

Petr Polovodov, Charlene Brillard, Olaf C Haenssler, Christophe Boyaval, D. Deresmes, Sophie Eliet, Fei Wang, Nicolas Clement, Didier Theron, Gilles Dambrine, Kamel Haddadi

Near-field scanning microwave microscopy (NSMM) is a scanning probe microscopy (SPM) technique that measures the local interaction of evanescent microwaves with a sample using a sharp tip probe. The traceability in NSMM is still challenging as the distribution of the electrical fields is affected…

Repeated photoporation with graphene quantum dots enables homogeneous labeling of live cells with extrinsic markers for fluorescence microscopy

Jing Liu, Ranhua Xiong, Toon Brans, Saskia Lippens, Eef Parthoens, Francesca Cella Zanacchi, Raffaella Magrassi, Santosh K Singh, Sreekumar Kurungot, Sabine Szunerits, Hannelore Bové, Marcel Ameloot, Juan Andrés A Fraire, Eline Teirlinck, Sangram Keshari Samal, Riet De Rycke, Gaëlle Houthaeve, Stefaan C de Smedt, Rabah Boukherroub, Kevin Braeckmans

In the replacement of genetic probes, there is increasing interest in labeling living cells with high-quality extrinsic labels, which avoid over-expression artifacts and are available in a wide spectral range. This calls for a broadly applicable technology that can deliver such labels unambiguously…

Thermodynamics of small systems with conformational transitions: The case of two-state freely jointed chains with extensible units

Manon Benedito, Stefano Giordano

Several experimental methods are usually applied for stretching single molecules and provide valuable insights about the static and dynamic responses induced by externally applied forces. This analysis is even more important for macromolecules exhibiting conformational transitions, thereby…

Optimized ohmic contacts for InAlGaN/GaN HEMTs

Farah Bouazzaoui, Marie Pierre Chauvat, Magali Morales, Malek Zegaoui, F Medjdoub, Piero Gamarra, Slawomir Kret, Pierre Ruterana

During the last years, the most significant improvement of the contact resistance forAlInN/GaN high electron mobility has been the use of a highly doped n+ GaN layer grown bymolecular beam epitaxy for the source and drain terminals. In a first report [1], the ohmiccontact processing was carried out…

Checksum-Filtered List Decoding Applied to H.264 and H.265 Video Error Correction

Firouzeh Golaghazadeh, Stephane Coulombe, François-Xavier Coudoux, Patrick Corlay

The latest video coding standards, H.264 and H.265, are highly vulnerable in error-prone networks. Reconstructed packets may exhibit significant degradation in terms of peak signal-to-noise ratio and visual quality. This paper presents a novel list-decoding approach exploiting the receiver side…

Improved Eigenfilter Design Method for Channel Shortening Equalizer in TH-UWB

Noureddine Benamara Benotmane, Sid Ahmed Elahmar, Iyad Dayoub, Walaa Hamouda

The large delay spread of ultra-wideband (UWB) channels causes intersymbol interference and therefore increases the complexity of a UWB Rake receiver. To resolve these problems, we present a new method for the design of channel shortening equalizers (CSE) in time-hopping UWB systems. Our proposed…

Graphene Doping Induced Tunability of Nanoparticles Plasmonic Resonances

Rana Nicolas, Gaëtan Lévêque, Pierre-Michel Adam, Thomas Maurer

Interest in graphene has been widely increasing since its discovery in 2004. Research on graphene for plasmonic applications has also boomed due to the high potential of these systems. In this article, we discuss the possible interaction between metallic NPs and graphene monolayer. We show how the…

Modeling and optimization of core (p-GaN)-multishell (i-InxGa1-xN/i-GaN/n-Al0.1Ga0.9N /n-GaN) nanowire for photovoltaic applications

Abdelkader Aissat, Fethi Benyettou, Isabelle Berbezier, Jean-Pierre Vilcot

In this work we report a modeling and optimization of a novel core (p-GaN)-multishell (i-InxGa1-xN/i-GaN/n-Al0.1Ga0.9N/n-GaN) coaxial NWs with a total length of about 3 μm and a radius of 0.19 μm. The variation of Indium composition in the i-InxGa1-xN active layer shows that x = 15% is the optimal…
