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…

Dual Photonic Structures Enable High‐Performance Semitransparent Organic Photovoltaics with Enhanced Light Utilization

Baozhong Deng, Youyang Shen, Kaiwen Zheng, Chi Wang, Gaëtan Lévêque, Tao Xu

Semitransparent organic photovoltaics (ST-OPVs) offer promising prospects for self-powered greenhouses and building-integrated photovoltaic systems. However, a remaining critical challenge is to balance the two competing indexes of power conversion efficiency (PCE) and average visible transmittance…

Mechanistic insights into the roles of graphene oxide and its derivatives in organic transformations – a review

Hamed Barzinmehr, Maryam Mirza-Aghayan, Rabah Boukherroub

Graphene oxide (GO) and functionalized graphene oxide (fGO), owing to their vast range of advantages, including simple preparation, low cost, recyclability, reusability, remarkable optical, electronic, and mechanical properties and the fact that they are environmentally friendly, have attracted…

Effects of functionalized magnetic graphene oxide on the visible-light-induced photocatalytic activity of perovskite-type MTiO3 (M= Zn and Mn) for the degradation of Rhodamine B

Anasheh Mardiroosi, Ali Reza Mahjoub, Amir Hossein Cheshme Khavar, Rabah Boukherroub, Mika Sillanpää, Parminder Kaur

This work reports the synthesis of a variety of perovskite-type titanates (MTiO3, M= Zn, and Mn) and their loading on functionalized magnetic graphene oxide (EDFG) to produce MTiO3@EDFG nanocomposites. These materials were fully characterized by FT-IR and Raman spectroscopy, XRD, SEM, TEM, N2…

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…

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…

A Quantum Annealing Solution to the Job Shop Scheduling Problem

Riad Aggoune, Samuel Deleplanque

We consider in this paper the job shop scheduling problem. We first present a mathematical formulation of the problem, namely a disjunctive model. Then, we show how the model can be reformulated as a Quadratic Unconstrained Binary Optimization (QUBO) problem, that can be solved by an analog quantum…

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-…
