Mathie Tenenbaum, Valérie Plaisance, Raphael Boutry, Valérie Pawlowski, Cécile Jacovetti, Clara Sanchez-Parra, Hélène Ezanno, Julien Bourry, Nicole Beeler, Gianni Pasquetti, Valery Gmyr, Stéphane Dalle, Julie Kerr-Conte, François Pattou, Syu-Ichi Hirai, Romano Regazzi, Amélie Bonnefond, Philippe Froguel, Amar Abderrahmani

Unveiling the key pathways underlying postnatal beta-cell proliferation can be instrumental to decipher the mechanisms of beta-cell mass plasticity to increased physiological demand of insulin during weight gain and pregnancy. Using transcriptome and global Serine Threonine Kinase activity (STK)...

Development of broadband high-frequency piezoelectric micromachined ultrasonic transducer array

Xu-Bo Wang, Le-Ming He, You-Cao Ma, Wen-Juan Liu, Wei-Jiang Xu, Jun-Yan Ren, Antoine Riaud, Jia Zhou

Piezoelectric micromachined ultrasonic transducers (PMUT) are promising elements to fabricate a two-dimensional (2D) array with a pitch small enough (approximately half wavelength) to form and receive arbitrary acoustic beams for medical imaging. However, PMUT arrays have so far failed to combine...

High-Q silicon nitride drum resonators strongly coupled to gates

Xin Zhou, Srisaran Venkatachalam, Ronghua Zhou, Hao Xu, Alok Pokharel, Andrew Fefferman, Mohammed Zaknoune, Eddy Collin

Silicon nitride (SiN) mechanical resonators with high quality mechanical properties are attractive for fundamental research and applications. However, it is challenging to maintain these mechanical properties while achieving strong coupling to an electrical circuit for efficient on-chip integration...

Surface modes in plasmonic stubbed structures

Y. Rezzouk, M. Amrani, S. Khattou, E.H. El Boudouti, Bahram Djafari-Rouhani

We present an analytical and numerical study about the existence of surface localized modes, known as Tamm states, in a one-dimensional (1D) comb-like plasmonic band gap structure. Surface plasmon polaritons (SPPs) waveguides with coupled resonators have been widely studied in recent years, because...

Plasmonic demultiplexer based on induced transparency resonances: Analytical and numerical study

E.H. El Boudouti, Bahram Djafari-Rouhani, M. Amrani, S. Khattou, A. Noual

We study both analytically and numerically the possibility to realize a simple plasmonic Y-shaped demultiplexer made of an input line and two output lines. Each line consisting of a metal-insulator-metal (MIM) waveguide contains a specific resonator made of two stubs grafted at a given position...

Induced transparency based subwavelength acoustic demultiplexers

T. Gu, Y. Cheng, Z. Wen, E.I.H. Ei Boudouti, Y. Jin, Y. Li, Bahram Djafari-Rouhani

Wave demultiplexers transporting desired wavelengths towards proper directions or ports are attracting numerous interests and applications in both physical and engineering areas. In acoustics, there is still a lack of compact and simple designs to achieve demultiplexers in three-port systems. In...

First-principles thermal transport in amorphous Ge 2 Sb 2 Te 5 at the nanoscale

Thuy-Quynh Duong, Assil Bouzid, Carlo Massobrio, Guido Ori, Mauro Boero, Évelyne Martin

Achieving a precise understanding of nanoscale thermal transport in phase change materials (PCMs), such as Ge 2 Sb 2 Te 5 (GST), is the key of thermal management in nanoelectronics, photonic and neuromorphic applications using non-volatile memories. By resorting to a first-principles approach to...

Monte Carlo analysis of the influence of surface charges on GaN asymmetric nanochannels: bias and temperature dependence

E. Pérez-Martín, I. Íñiguez-De-La-Torre, Christophe Gaquière, T. González, J. Mateos

In this paper, the occupancy of sidewall surface states having a clear signature in the performance of AlGaN/GaN-based self-switching diodes (SSDs) is analyzed using a semi-classical Monte Carlo (MC) simulator in a wide temperature ( T) range, from 100 to 300 K. Experimental I- V curves show an...
