Vertical and lateral manipulation of single Cs atoms on the semiconductor InAs(111)A

Rian A. M. Ligthart, L. Desplanque, X. Wallart, Ingmar Swart, Christophe Coinon

The tip of the scanning tunneling microscope can be used to position atoms and molecules on surfaces with atomic scale precision. Here, we report the controlled vertical and lateral manipulation of single Cs atoms on the InAs(111)A surface. The Cs adatom adsorbs on the In-vacancy site of the InAs(...

Short-time expansion of one-dimensional Fokker-Planck equations with heterogeneous diffusion

Tom Dupont, Stefano Giordano, Fabrizio Cleri, Ralf Blossey

We formulate a short-time expansion for one-dimensional Fokker-Planck equations with spatially dependent diffusion coefficients, derived from stochastic processes with Gaussian white noise, for general values of the discretization parameter 0 ⩽ α ⩽ 1 of the stochastic integral. The kernel of the...

Tunable topologically protected waveguiding in auxetic nonlinear metamaterials

M. Morvaridi, F. Bosia, M. Brun, V.F. Dal Poggetto, A.S. Gliozzi, M. Miniaci, C. Croenne, N.M. Pugno, G. Carta

In this paper, we discuss the possibility of achieving tunable topologically protected edge modes through the application of uniaxial prestrain in an auxetic metamaterial. The proposed structure consists of a thin slab with oriented cuts in a hexagonal lattice, where topologically protected band...

Optimizing Connectivity: DVB-RCS2 Uplink to GEO Satellites via Optical Wireless Communication

Meryem Romaissa Djellouli, Sid Ahmed Chouakri, Abdelkrim Ghaz, Abdelmalik Taleb-Ahmed

This research focuses on the integration of an opto-satellite system based on Free Space Optical Communication (OWC) within DVB-RCS2 chains, implementing 16-QAM modulation techniques and Optical Time Division Wavelength Multiplexing (OTDMWDM). A co-simulation framework combining the MATLAB and...

FT-IR detection of DMMP on TiO 2 -Modified Porous Silicon Substrates

Warda Raiah, M. Guendouz, Parastesh Pirasteh, Vincent Thomy, Joël Charrier, Yannick Coffinier

In this study, we present a new chemical sensor based on a functionalized porous silicon and sensitive to dimethyl methyl phosphonate (DMMP), a simulant of sarin gas, known as one of the most toxic warfare agents. The porous silicon was prepared by anodising a boron-doped p-Si (100) wafer. A metal...

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...

A Tight-Binding Model for Illustrating Exciton Confinement in Semiconductor Nanocrystals

Z. Hens, Christophe Delerue

The Brus equation describes the relation between the lowest energy of an electron–hole pair and the size of a semiconductor crystallite. However, taking the strong confinement regime as a starting point, the equation does not cover the transition from weak to strong confinement, the accompanying...

Enabling Low-Power Signature Recognition for the IoT with SLIF neurons

Guillaume Marthe, Claire Goursaud, Laurent Clavier

Energy constraints are still a significant challenge in numerous IoT applications, particularly due to the excessive power consumption of microcontrollers. To overcome this limitation, novel circuit designs have been introduced, with the integration of spiking neurons and analog computing emerging...
