Conduction Band Fine Structure in Colloidal HgTe Quantum Dots

Margaret Hudson, Menglu Chen, Vladislav Kamysbayev, Eric Janke, Xinzheng Lan, Guy Allan, Christophe Delerue, Byeongdu Lee, Philippe Guyot-Sionnest, Dmitri Talapin

Abstract HgTe colloidal quantum dots (QDs) are of interest because quantum confinement of semimetallic bulk HgTe allows one to synthetically control the bandgap throughout the infrared. Here, we synthesize highly monodisperse HgTe QDs and tune their doping both chemically and electrochemically. The…

Strain-mediated all-magnetoelectric memory cell

Vladimir Preobrazhensky, L. Krutyansky, Nicolas Tiercelin, Yannick Dusch, A. Sigov, Philippe Pernod, Stefano Giordano

Downscaling of magnetoelectric random access memory device (MELRAM) is considered by studying an example of the hybrid structure based on ferroelectric-magnetostrictive metal. Elastic mechanism of magnetoelectric interaction is analyzed by numerical modeling taking into account inhomogeneous…

Influence of the magnetic state on the voltage-controlled magnetoelectric effect in a multiferroic artificial heterostructure YIG/PMN-PZT

Jianyun Lian, Freddy Ponchel, Nicolas Tiercelin, Liuyang Han, Ying Chen, Denis Remiens, Tuami Lasri, Genshui Wang, Philippe Pernod, Wenbin Zhang, Xianlin Dong

The artificial multiferroic heterostructure used in this work is composed by an yttrium iron garnet (YIG) film deposited by radio frequency (rf) magnetron sputtering on a metalized PMN-PZT ceramic. We demonstrate, thanks to the well-known converse magnetoelectric (CME) coupling, the control of the…

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…

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…
