Impact of Transducer Aspect Ratio on the performance of AlN Hybrid SAW/BAW Resonators

S. Barsoum, A. Schembri, M. Bernard, A. Lefevre, M. Bousquet, A. Reinhardt, T. Laroche, S. Ballandras, B. Dubus

In this study, we investigate the impact of the aspect ratio of transducers on the electromechanical coupling factor k2t of hybrid SAW/BAW (HSB) resonators. Finite element calculations of the harmonic admittance suggest that the optimum k2t for the two modes of interest of these devices, are…

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…

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…

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…

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…
