Phonons in Slow Motion: Dispersion Relations in Ultra-Thin Si Membranes

John Cuffe, Emigdio Chavez, Andrey Shchepetov, Pierre-Olivier Chapuis, El Houssaine El Boudouti, Francesc Alzina, Timothy Kehoe, Jordi Gomis-Bresco, Damian Dudek, Yan Pennec, Bahram Djafari-Rouhani, Mika Prunnila, Jouni Ahopelto, Clivia. M. Sotomayor Torres

We report the changes in dispersion relations of hypersonic acoustic phonons in free-standing silicon membranes as thin as \sim 8 nm. We observe a reduction of the phase and group velocities of the fundamental flexural mode by more than one order of magnitude compared to bulk values. The…

Phononic and photonic properties of a stubbed strip waveguide

Yan Pennec, Bahram Djafari-Rouhani, Mourad Oudich, Said El-Jallal, Josemaria Escala, Alejandro Martinez, Vincent Laude

Many studies have been devoted to the search of photonic and phononic band gaps, but relatively few works are dealing with the simultaneous control of phonons and photons. Phoxonic structures hold promises for the simultaneous confinement and tailoring of sound and light waves with potential…

Structure and electrical properties in the K1/2Bi1/2TiO3-K1/2Bi1/2ZrO3 solid solution (KBT-KBZ)

M. Bengagi, François Morini, M. El Maaoui, Pascal Marchet

The present work is devoted to the study of the Zr 4þ /Ti 4 substitution in the K1/2Bi1/2Ti(1-x)ZrxO3 solid solution (x ¼ 0.0 to x ¼ 1.0), based upon the K1/2Bi1/2TiO3 (KBT) ferroelectric compound. The tetragonal distortion of KBT is suppressed by this substitution and leads to the cubic compound…

First demonstration of high-power GaN-on-silicon transistors at 40 GHz

F Medjdoub, Malek Zegaoui, B. Grimbert, Damien Ducatteau, N. Rolland, Paul-Alain Rolland

In this letter, high-output-power-density GaN-based high-electron-mobility transistors grown on a 100-mm silicon substrate is demonstrated for the first time at 40 GHz. The use of an optimized double heterostructure based on ultrathin barrier AlN/GaN allows both high current density and low leakage…
