Alternative strategy to grow large surface hBN on Ge films by molecular beam epitaxy

Walter Batista Pessoa, Max Franck, Jaroslaw Dabrowski, X. Wallart, Nicolas Nuns, Mindaugas Lukosius, Dominique Vignaud

Hexagonal Boron Nitride is a two-dimensional insulator with a wide bandgap (~6 eV), chemically and thermally stable. Its 2D nature makes it exceptionally interesting as an ultrathin barrier, tunneling or passivation layer for integrated electronics and photonics, noticeably for the encapsulation of…

PFM and s-SNOM imaging of minimally-twisted double bilayer graphene: moirés, domain walls and solitons

Pauline de Crombrugghe, Cristiane Nascimento Santos, Yuanzhuo Hong, Sambit Mohapatra, Watanabe K., Taniguchi T., Jean-Francois Lampin, Rebeca Ribeiro, Bernard Nysten, Benoit Hackens

Twisting graphene-based heterostructures results in local atomic reconstructions which have large consequences in terms of local and global electronic and optical properties [1]. At small twist angle, the moiré superstructure relaxes by forming domains with homogeneous atomic ordering, separated by…

Robustness to imperfect CSI of power allocation policies in cognitive relay networks

Yacine Benatia, Romain Negrel, Anne Savard, E Veronica Belmega

In this paper, the aim is to study the robustness against imperfect channel state information (CSI) of the power allocation policies maximizing the constrained and non-convex Shannon rate problem in a relay-aided cognitive radio network. The primary communication is protected by a Quality of…

Modélisation Physique d'Interrupteur Moléculaire, Physikalische Modellierung von molekularen Schaltern, Physical Modeling of molecular Switches

Christophe Krzeminski

Cette modeste communication scientifique présente les résultats de modélisation théorique menés sur différentes classes d’interrupteur moléculaire. Initialement, la définition d'un interrupteur moléculaire est un composé bistable c'est-à-dire existant sous la forme de deux états distincts…, This modest communication presents the results of the theoretical modelling of various molecular switches. Initialy, a molecular switch was defined as a bistable compound existing in two different states (open) or (closed) with the influence of a optical stimuli allowing the modulation of the…

[Invited] Challenges to measure RF noise and intermodulation performances of mmW/THz devices

Francois Danneville, Haitham Ghanem, Joao Carlos Azevedo Gonçalves, Sylvie Lepilliet, Daniel Gloria, Guillaume Ducournau

Applications in millimetre wave range and terahertz frequencies keep on increasing. In this context, drastic challenges are faced at measurement level, in particular to extract noise performance and nonlinear properties of devices and circuits used to build the required systems. The aim of this…

Optimization with Quantum Annealing Machines

Samuel Deleplanque

Quantum annealing is a method based on simulated annealing where temperature variations are replaced by quantum fluctuations that cause qubit state transitions. ISING problems and Quadratic Unconstrained Binary Optimization problems (QUBO) can be tackled by quantum annealing-based machines. We can…
