Raman thermometry characterization of GeSbTe based phase change materials

Akash Patil, Yannick Le-Friec, Jury Sandrini, Roberto Simola, Simon Jeannot, Philippe Boivin, Emmanuel Dubois, J.F. Robillard

Phase change materials for embedded memory automotive applications are dynamically evolving with the aim of high temperature data retention [1]. This requires higher crystallization temperature and amorphous phase stability, which was achieved by increasing the Germanium content and doping with…

Spectroscopie vibrationnelle à la nano-échelle en STEM : étude des effets d’altération spatiale sur la signature IR de l’astéroïde Ryugu

Sylvain Laforet, Hugues Leroux, Corentin Le Guillou, Francisco de la Peña, Maya Marinova, Damien Jacob, Jean-Christophe Viennet, Bahae-Eddine Mouloud, Daniel Hallatt, Adrien Teurtrie, Mario Pelaez Fernandez, Mike Walls, L. Galvao-Tizei, David Troadec

Le récent développement de microscopes électroniques monochromatés dédiés à la spectroscopie EELS à haute résolution met sur le devant de la scène la possibilité d’atteindre la gamme spectrale de l’infrarouge moyen avec, au mieux, une résolution spectrale de 40 cm-1 [1]. Cette technique ouvre une…

Space weathering influence on Ryugu’s IR signature: insights from nanoscale vibrational spectroscopy in the STEM

Sylvain Laforet, Hugues Leroux, Corentin Le Guillou, Francisco de la Peña, Maya Marinova, Damien Jacob, Jean-Christophe Viennet, Bahae-Eddine Mouloud, Daniel Hallatt, Adrien Teurtrie, Mario Pelaez Fernandez, Mike Walls, L. Galvao-Tizei, David Troadec

JAXA’s Hayabusa2 mission brought back 5.4 g of material from the surface of the carbonaceous asteroid Ryugu. Some grains show evidence of a modified surface attributed to space-weathering effects [1], which result from solar-wind irradiation and/or micrometeoroid bombardment. In collaboration with…

On the Practical Limitations for the Generation of Gunn Oscillations in Highly Doped GaN Diodes

S. García-Sánchez, M. Abou Daher, M. Lesecq, L. Huo, R. Lingaparthi, D. Nethaji, K. Radhakrishnan, I. Íñiguez-De-La-Torre, B. Vasallo, S. Pérez, T. González, J. Mateos

Planar Gunn diodes based on doped GaN active layers with different geometries have been fabricated and characterized. Gunn oscillations have not been observed due to the catastrophic breakdown of the diodes for applied voltages around 20–25 V, much below the bias theoretically needed for the onset…

Solving 3SAT and MIS Problems with Analog Quantum Machines

Samuel Deleplanque

This work considers the use of analog quantum machines to solve the boolean satisfiability problem 3SAT by taking Quadratic Unconstrained Binary Optimization models (QUBO) as input. With the aim of using real quantum computers instead of emulators to solve instances of the problem, we choose the D-…
