Atomistic insights into the nucleation and growth of hexagonal boron nitride and graphene heterostructures

Mohamed Achehboune, Kazem Zhour, Jaroslaw Dabrowski, Dominique Vignaud, Max Franck, Mindaugas Lukosius, Jean-François Colomer, Luc Henrard

Graphene and hexagonal boron nitride (hBN) are two-dimensional (2D) materials with a similar atomic structure but drastically different although complementary electronic properties. The large-scale synthesis of h-BN/graphene heterostructures with high crystallographic quality is required to fully…

Experimental closed-loop flow separation control: Data- and phenomenological-driven approaches

T. Arnoult, G. Acher, V. Nowinski, P. Vuillemin, C. Briat, P. Pernod, C. Ghouila-Houri, A. Talbi, E. Garnier, C. Poussot-Vassal

Flow control aims at modifying a natural flow state to reach an other flow state considered as advantageous. In this paper, active feedback flow separation control is investigated with two different closed-loop control strategies, involving a reference signal tracking architecture. Firstly, a data-…

On the reduction of gas permeation through the glass windows of micromachined vapor cells using Al₂O₃ coatings

C. Carlé, A. Mursa, P. Karvinen, S. Keshavarzi, M. Abdel Hafiz, V. Maurice, R. Boudot, N. Passilly

Stability and precision of atomic devices are closely tied to the quality and stability of the internal atmosphere of the atomic vapor cells on which they rely. Such an atmosphere can be stabilized by building the cell with low permeation materials such as sapphire or aluminosilicate glass in…

Autonomous radar interference detection and mitigation using neural network and signal decomposition

Dayat Kurniawan, Budiman Putra Asmaur Rohman, Ratna Indrawijaya, Chaeriah Bin Ali Wael, Suyoto Suyoto, Purwoko Adhi, Iman Firmansyah

Autonomous radar interference is a challenging problem in autonomous vehicle systems. Interference signals can decrease the signal-to-interference-noise ratio (SINR), and this condition decreases the performance detection of autonomous radar. This paper exploits a neural network and signal…

Immunity to Backscattering of Bulk Waves in Topological Acoustic Superlattices

P A Deymier, Jérome O Vasseur, K. Runge, A. Khanikaev, A. Alù

We herein investigate the scattering of orthogonal counterpropagating waves and one-way propagating bulk waves in discrete acoustic superlattices subjected to a scattering potential applied to one of the superlattice unit cells. We demonstrate theoretically that the orthogonality of…

500 GHz operational bandwidth MUTC-photodiodes with milliwatt terahertz output power levels

Ezgi Abacıoğlu, Marcel Grzeslo, Tom Neerfeld, Abdu Subahan Mohammed, J L F Estévez, Guillaume Ducournau, Andreas Stöhr

We present waveguide-integrated 1.55 μm InP-based modified uni-travelling-carrier photodiodes (MUTC-PDs) featuring coplanar waveguide outputs. The fabricated photodiodes yield an operational bandwidth of 500 GHz and milliwatt output power levels in the lower THz domain.
