Improvement of linearity in trap-rich substrates for radio frequency applications: Which of donor and acceptor trap is the best?

Justine Philippe, Jean-François Robillard, Daniel Gloria, Emmanuel Dubois

This paper investigates the effect of volume traps intentionally introduced into a silicon-on-insulator (SOI) substrate by inserting a layer of polysilicon beneath buried oxide. In radio frequency applications, this type of substrate, referred to as trap-rich, is known to considerably reduce the…

Creative Mind: Hyperconnected or Disconnected ?, Créativitée: hyperconnectée ou déconnectée ?

Christophe Krzeminski

Creativity is the subject of many views. In liberal viewpoint, creativity is considered as the core of the "economical competitivity" being a key driver in terms of change rate and economical growth. The intellectual vision often seen creativity as a reflection, a mirror of our…

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(…

2D Rhenium- and Niobium-Doped WSe₂ Photoactive Cathodes in Photo-Enhanced Hybrid Zn-Ion Capacitors

Monaam Benali, Jalal Azadmanjiri, Martin Loula, Zhongquan Liao, Rui Gusmão, Amutha Subramani, Kalyan Jyoti Sarkar, Rabah Boukherroub, Zdeněk Sofer

Designing a multifunctional device that combines solar energy conversion and energy storage is an appealing and promising approach for the next generation of green power and sustainable society. In this work, we fabricated a single-piece device incorporating undoped WSe$_2$, Re- or Nb-doped WSe$_2…

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…

Robust automotive radar interference mitigation using multiplicative-adaptive filtering and Hilbert transform

Budiman Putra Asmaur Rohman, Arief Suryadi Satyawan, Dayat Kurniawan, Ratna Indrawijaya, Chaeriah Bin Ali Wael, Nasrullah Armi

Radar is one of the sensors that have significant attention to be implemented in an autonomous vehicle since its robustness under many possible environmental conditions such as fog, rain, and poor light. However, the implementation risks interference because of transmitting and/or receiving radar…

Interdigitated-comb piezoelectric phononic crystals for innovative SAW devices

R. Alcorta Galván, C. Croënne, B. Dubus, E. Eustache, A. Ngabonziza, A.-C. Hladky-Hennion

In this paper, piezoelectric phononic crystals made up of interdigitated combs in floating potential condition are studied. Calculation of the dispersion curves shows that, in addition to Bragg bandgaps due to the presence of periodic electrodes, supplementary bandgaps are present corresponding to…

Self-sustained optomechanical state destruction triggered by the Kerr nonlinearity

A Delattre, I Golokolenov, R Pedurand, Xin Zhou, A Fefferman, E Collin

Cavity optomechanics implements a unique platform where moving objects can be probed by quantum fields, either laser light or microwave signals. With a pump tone driving at a frequency above the cavity resonance, self-sustained oscillations can be triggered at large injected powers. These limit…

Thermoelectric characterization of crystalline nano-patterned silicon membranes

Hafsa Ikzibane, Akash Patil, Jon Canosa Diaz, Etienne Okada, Etienne Blandre, Emmanuel Dubois, Jean-François Robillard

Research towards efficient and environmentally friendly thermoelectrics proposes silicon nanostructures as possible candidates through reduction of the phononic thermal conductivity. However, there is scarce literature about experimental measurements of the thermoelectric figure-of-merit zT on…

A new metric for the comparison of permittivity models in terahertz time-domain spectroscopy

Mélanie Lavancier, Nabil Vindas-Yassine, Juliette Vlieghe, Theo Hannotte, François Orieux, Romain Peretti

We present a robust method, as well as a new metric, for the comparison of permittivity models in terahertz timedomain spectroscopy (THz-TDS). In this work, we perform an extensive noise analysis of a THz-TDS system, we remove and model the unwanted deterministic noises and implement them into our…
