Ambipolar spin diffusion in p-type GaAs: A case where spin diffuses more than charge

Fabian Cadiz, V. Notot, J. Filipovic, D. Paget, C. Weber, L. Martinelli, A. Rowe, S. Arscott

We investigate the diffusion of charge and spin at 15 K in p-type GaAs, combining transient-grating and energy-resolved microluminescence measurements to cover a broad range of photoelectron density. At very low optical power, in a unipolar nondegenerate regime, charge and spin diffuse at the same…

Advancements on the molecular design of nanoantibiotics: current level of development and future challenges

Roxana Jijie, Alexandre Barras, Florina Teodorescu, Rabah Boukherroub, Sabine Szunerits

Numerous antimicrobial drugs have been developed and commercialized to kill and inhibit the growth of pathogenic microbes. The therapeutic efficiency of these drugs has however become often inadequate for the treatment of microbial infections, the reasons being multiple. Oral administration results…

A comprehensive study of magnetic exchanges in the layered oxychalcogenides Sr3Fe2O5Cu2Q2 (Q = S, Se)

Minfeng Lü, Olivier Mentre, Elijah E. Gordon, Myung-Hwan Whangbo, Alain Wattiaux, Mathieu Duttine, Nicolas Tiercelin, Houria Kabbour

The layered oxysulfide Sr3Fe2O5Cu2S2 was prepared, and its crystal structure and magnetic properties were characterized by synchrotron X-ray diffraction (XRD), powder neutron diffraction (PND), Mössbauer spectroscopy measurements and by density functional theory (DFT) calculations. In addition, the…

Topological protection of electronic states against disorder probed by their magnetic moment

Athmane Tadjine, Christophe Delerue

Magnetic moments (MMs) of electrons in topological insulator quantum dots (TI-QDs) are investigated using a model system, namely a multiorbital honeycomb lattice. Their nature and orientation with respect to the spin are studied. We show that large MMs are not specific to edge states in nontrivial…

A 65-nm CMOS 7fJ per synaptic event clique-based neural network in scalable architecture

Benoit Larras, Paul Chollet, Cyril Lahuec, Fabrice Seguin, Matthieu Arzel

Clique-based neural networks are less complex than commonly used neural network models. They have a limited connectivity and are composed of simple functions. They are thus adapted to implement neuro-inspired computation units operating under severe energy constraints. This paper shows an ST 65-nm…

Approach-to-equilibrium molecular dynamics

Évelyne Martin, Pier Luca Palla, H. Zaoui, Fabrizio Cleri

Besides steady-state methods presented in Chapters 8 and 9, molecular dynamics simulations can also be used to simulate temperature transients, by means of approach-to-equilibrium molecular dynamics (AEMD) calculations. The interest for such methods is materialso the short MD simulation time…

Vibration de bulles en armure non sphériques

Michael Baudoin, Gaurav Prabhudesai, Ilyesse Bihi, Farzam Zoueshtiagh, Johny Jose

Les bulles en armures (des bulles couvertes par une monocouche de particules partiellement mouillantes) possèdent des propriétés fascinantes telles qu'une stabilité accrue vis à vis de leur dissolution ou leur capacité à conserver des formes non sphériques. Ces bulles peuvent être produites en…

Combined scanning microwave and electron microscopy: a novel toolbox for hybrid nanoscale material analysis

Kamel Haddadi, O. C. Haenssler, K. Daffe, S. Eliet, Christophe Boyaval, Didier Theron, Gilles Dambrine

A novel toolbox for hybrid nanoscale material characterization is presented. The system consists of a nano-robotic, compact and modular near-field scanning microwave microscope (NSMM) integrated into a high resolution scanning electron microscope (SEM). The instrument developed can perform hybrid…
