6.9 GHz Film Bulk Acoustic Resonator based on Pulsed Laser Deposited LiNbO3 Film

L.C. Sauze, N. Vaxelaire, R. Templier, F. Pierre, C. Maeder-Pachurka, J. Delprato, D. Remiens, G. Rodriguez, M. Bousquet, F. Dupont

In this work, 200 nm-thick LiNbO 3 layers have been grown on Ru/Si and Pt/Si substrates using an industrialized Pulsed Laser Deposition (PLD) system. Film’s properties have been investigated by means of X-Ray Diffraction (XRD), Atomic Force Microscopy (AFM), Scanning Electron Microscopy (SEM), and…

Electrolyte ohmic heating during electrodeposition: The role of coupled kinetic-transport phenomena that lead to morphological and microstructural changes

Pınar Eribol, Sarathy Gopalakrishnan, S.V. Diwakar, Abdelkrim Talbi, Ranga Narayanan, Farzam Zoueshtiagh, Kirk Ziegler

Understanding the morphological changes to the electrodes during electrochemical processes is important to many fields. These morphological changes often lead to dendrite formation and significant heat generation that can be detrimental to the process, especially the performance and lifetime of…

Non-Volatile Bipolar TiN/LaMnO3/Pt Memristors with Optimized Performance

Raquel Rodriguez-Lamas, Dolors Pla, Caroline Pirovano, Odette Chaix-Pluchery, Carlos Moncasi, Michel Boudard, Rose-Noëlle Vannier, Carmen Jiménez, Mónica Burriel

LaMnO 3+δ (LMO) perovskite is a very interesting candidate for Valence Change Memories due to its flexible stoichiometry, accommodated through the Mn +3 /Mn +4 equilibrium, at the origin of significant resistivity changes. Here, the successful combination of a LMO layer, with a top active TiN…

High‐Throughput Computing Guided Low/High Index Optical Coupling Layer for Record‐Performance Semitransparent Organic Solar Cells

Tao Xu, Baozhong Deng, Yanglin Zhao, Zihan Wang, Gaëtan Lévêque, Yannick Lambert, Bruno Grandidier, Shenghao Wang, Furong Zhu

Semitransparent organic solar cells (ST‐OSCs) can be made in different colors, allowing light to pass through, and yet absorb enough visible and near‐infrared (NIR) light to generate electricity. However, it remains a challenge to achieve high performing ST‐OSCs over the two competing indexes of…

Terahertz time domain spectroscopy of a single split ring resonator coupled to an amino acid crystal

Théo Hannotte, Adrien Pillet, Noureddin Osseiran, Jean-Francois Lampin, Romain Peretti

Split Ring Resonators (SRRs) have been used in large arrays to interact with objects much smaller than the wavelength in the terahertz range. Using arrays of SRRs facilitates the measurements, but prevents one from extracting accurate information regarding the object properties in this frequency…

Structural Analysis of Nano Core PCF With Fused Cladding for Supercontinuum Generation in 6G Networks

Rajesh Anbazhagan, S. Chandru, Ravikumar Chinthaginjala, Kalapraveen Bagadi, Mohammad Alibakhshikenari, Bal Virdee, Syed Mansoor Ali, Iyad Dayoub, Patrizia Livreri, Sonia Aïssa

The Sixth Generation (6G) networks have identified the use of frequency range between 95 GHz and 3 THz with a targeted data rate of 1 Terabytes/second at the access network for holographic video applications. As is demands broadening of spectrum at the core network, this paper proposes a…

Asynchronous WPNC With DFT Precoding and Symbol-Spaced Processing

Petr Hron, Jan Sykora, Laurent Clavier

This letter addresses the problem of asynchronous reception in a 2-source Hierarchical MAC (H-MAC) in the context of a Wireless Physical Layer Network Coded (WPNC) system with a Hierarchical Decode and Forward (HDF) relaying strategy. In this work, we assume fractional symbol duration time delays…

Multi-user downlink NOMA systems aided by an ambient backscatter device: achievable rate region and energy-efficiency maximization

Hajar El Hassani, Anne Savard, E. Veronica Belmega, Rodrigo C. De Lamare

In this paper, we investigate the energy efficiency of a multiuser downlink Non-Orthogonal Multiple Acess (NOMA) system aided by an ambient backscatter device that modulates its own information by reflecting the incident signal coming from the NOMA transmitter. Because of the multiplicative…

Formation and highly directional output of long-lived resonances in photonic comblike structures

Leonard Dobrzyński, Housni Al-Wahsh, Abdellatif Akjouj, Eman Abdel-Ghaffar

Bound states in the continuum (BICs) and long-lived resonances have become a unique way to produce the extreme localization of light waves. In this paper, we present a theoretical demonstration of BICs and long-lived resonances in photonic comblike structures with two semi-infinite leads, together…
