A one-dimensional optomechanical crystal with a complete phononic band gap

J. Gomis-Bresco, D. Navarro-Urrios, M. Oudich, Said El-Jallal, A. Griol, D. Puerto, E. Chavez, Yan Pennec, Bahram Djafari-Rouhani, F. Alzina, A. Martínez, C.M. Sotomayor Torres

Recent years have witnessed the boom of cavity optomechanics, which exploits the confinement and coupling of optical and mechanical waves at the nanoscale. Among their physical implementations, optomechanical (OM) crystals built on semiconductor slabs enable the integration and manipulation of…

Thermoelectric infrared microsensors based on a periodically suspended thermopile integrating nanostructured Ge/SiGe quantum dots superlattice

Katir Ziouche, G. Savelli, Zahia Bougrioua, D. Hauser, P. Lejeune, P.M. Michon, Tuami Lasri, Didier Leclercq

This paper presents an original integration of polycrystalline SiGe-based quantum dots superlattices (QDSL) into Thermoelectric (TE) planar infrared microsensors (μSIR) fabricated using a CMOS technology. The nanostructuration in QDSL results into a considerably reduced thermal conductivity by a…

Unconventional thin-film thermoelectric converters : structure, simulation, and comparative study

Maciej Haras, Valeria Lacatena, Stéphane Monfray, J.F. Robillard, Thomas Skotnicki, Emmanuel Dubois

Bi2Te3 or Sb2Te3 are the materials most widely used in thermoelectric generators (TEG) operating near room temperature. These materials are, however, environmentally harmful, expensive, and incompatible with complementary metal-oxide semiconductor technology, in contrast to silicon (Si), germanium…

Flat THz launcher antenna

Unai Beaskoetxea, Miguel Beruete, Mokhtar Zehar, Amit Agrawal, Shuchang Liu, Karine Blary, Abdallah Chahadih, Xiang-Lei Han, David Etayo, Miguel Navarro-Cia, Ajay Nahata, Tahsin Akalin, Mario Sorolla

1D and 2D leaky-wave corrugated antennas working at terahertz frequencies are numerically and experimentally studied. These structures allow temporal-pulse and beam shaping by engineering the leakage rate of the surface waves induced by the corrugations

On the correlation between kink effect and effective mobility in InAlN/GaN HEMTs

Philippe Altuntas, N. Defrance, Marie Lesecq, Alain Agboton, Rezki Ouhachi, Etienne Okada, Christophe Gaquière, Jean-Claude de Jaeger, Éric Frayssinet, Yvon Cordier

This paper reports on the kink effect observed in InAlN/GaN high electron mobility transistors. Electrical characterizations were carried out to point out the influence of this phenomenon on transistor behaviour. It is demonstrated that the kink effect is directly correlated to shallow traps…

Theory and simulation of optomechanical effects in phoxonic crystals

Said El-Jallal, Mourad Oudich, Yan Pennec, Abdelkader Makhoute, Jordi Gomis-Bresco, Daniel Navarro-Urrios, Clivia M. Sotomayor Torres, Alejandro Martínez, Bahram Djafari-Rouhani

Phoxonic crystals are periodic structures that can exhibit dual phononic and photonic band gaps, thus allowing the simultaneous confinement of both acoustic and optical waves inside the same defect such as a cavity or a waveguide. Then, one can expect an enhancement of the phonon-photon interaction…

Epitaxial hexagonal boron nitride on Ir(111) : a work function template

Fabian Schulz, Robert Drost, Sampsa K. Hämäläinen, Thomas Demonchaux, Ari P. Seitsonen, Peter Liljeroth

Hexagonal boron nitride (h-BN) is a prominent member in the growing family of two-dimensional materials with potential applications ranging from being an atomically smooth support for other two-dimensional materials to templating growth of molecular layers. We have studied the structure of…
