Macro and nanoscale properties of (001)-oriented Bi_0.5Na_0.5TiO₃ lead-free piezoelectric thin films grown by sputtering on LaNiO₃/Si substrates

Saj Mohan Mohandas Moolayil, Arthur Hamieh, Antonio da Costa, Anthony Ferri, Rachel Desfeux, Denis Rémiens

In this paper, the effect of the post-annealing temperature on the structural and electrical properties at macro and nanoscale of Sodium Bismuth Titanate - Bi_0.5Na_0.5TiO₃ (BNT) films is reported. Stoichiometric BNT thin films were…

[HDR] Collective matter excitations at THz frequencies and their applications for innovative THz photonic devices, Collective matter excitations at THz frequencies and their applications for innovative THz photonic devices

Mathias Vanwolleghem

This Habilitation memoir gives a complete overview of my research activities since my PhD diploma in May 2005. During these 18 years of research (of which 16 as tenured CNRS researcher), I have been conducting my research in two different research laboratories: from 2005 until 2012 in the IEF…

Guidelines for Overcoming the Practical Limitations for the Fabrication of THz Sources with GaN Planar Gunn Diodes

Javier Mateos, S. García-Sánchez, Mahmoud ABOU DAHER, Marie Lesecq, L. Huo, R. Lingaparthi, D. Nethaji, K. Radhakrishnan, Ignacio Íñiguez-De-La-Torre, B. García-Vasallo, S. Pérez, T. González

Gunn oscillations are expected to appear in GaN at high electric fields due to its negative differential mobility, but they have never been observed experimentally due to the large voltages to be applied. We propose a way to avoid such practical problems by fabricating planar Gunn diodes with…

A G-band Packaged Amplified Noise Source using SiGe BiCMOS 55 nm Technology

Victor Fiorese, Joao Carlos Azevedo Goncalves, Simon Bouvot, Sylvie Lepilliet, Daniel Gloria, Guillaume Ducournau, Christophe Gaquière, Emmanuel Dubois

This article introduces the first BiCMOS SiGe technology based packaged noise source (NS) operating in G-band (140-220 GHz). An amplified PN junction diode has been packaged and biased in avalanche mode to generate Excess Noise Ratios (ENRav) of approximately 25 dB between 140 and 170 GHz at…

Tilt-related alignment issues in miniature micromechanical on-wafer electrical probes composed of multiple flexible microcantilevers

Steve Arscott

Abstract Some new issues concerning the contacting and positioning of small electrical microelectromechanical systems (MEMS) probes based on multiple, flexible microcantilevers are presented here. A tilt error, associated with the lateral probe roll, means that contact touchdown occurs sequentially…

Electromechanical sensitivity of ZnO thin films at high-pressure regime for SAW strain sensor applications

Fahima Arab, Fares Kanouni, Rafik Serhane, Yan Pennec

This paper employs Density Functional Theory (DFT) to investigate the influence of high hydrostatic pressure on the piezo-elastic properties of ZnO with a specific focus on its repercussions for Surface Acoustic Wave (SAW) devices. Our findings reveal a significant enhancement in the piezoelectric…

Control of microstructure and composition of reactively sputtered vanadium nitride thin films based on hysteresis curves and application to microsupercapacitors

Allan Lebreton, Marie-Paule Besland, Pierre-Yves Jouan, Tatiana Signe, Cédric Mannequin, Mireille Richard-Plouet, Maryline Le Granvalet, Christophe Lethien, Thierry Brousse, Jérémy Barbé

Vanadium nitride (VN) thin films were prepared by reactive DC magnetron sputtering of a vanadium target using nitrogen as reactive gas. The structural, morphological, and compositional evolution of these films is described based on hysteresis diagrams plotting the sputtering power versus nitrogen…

Exceptional points for crack detection in non-Hermitian beams

Yabin Jin, Wenjun Li, Bahram Djafari-Rouhani, Yan Li, Yanxun Xiang

We study exceptional points (EPs) in parity-time (PT) symmetric non-Hermitian beams and explore their applications in crack detection. The EPs are formed by coupling different beam modes under feedback-controlled forces. The variations of the required non-Hermitian coefficient for the achievement…
