Physical Insights of thin AlGaN Back Barrier for millimeter-wave high voltage AlN/GaN on SiC HEMTs

Ajay Shanbhag, Francois Grandpierron, Kathia Harrouche, Farid Medjdoub

In this work, physical mechanisms underlying carbon-doped buffer combined with an AlGaN back-barrier layer are investigated in state-of-the-art millimeter-wave AlN/GaN transistors. We have fabricated devices with and without the insertion of a thin AlGaN back-barrier layer with reduced carbon…

Hermitian and non-Hermitian Weyl physics in synthetic three-dimensional piezoelectric phononic beams

Liangshu He, Yan Li, Bahram Djafari-Rouhani, Yabin Jin

Recently, the evolution of the Weyl point (WP) caused by the introduction of nonhermiticity into Weyl semimetals has aroused great research interest. We consider elastic flexural wave propagation in a phononic beam containing piezoelectric materials and introduce nonhermiticity through active…

Capillary-driven horseshoe vortex forming around a micro-pillar

K. Ozawa, H. Nakamura, K. Shimamura, G.F. Dietze, H.N. Yoshikawa, Farzam Zoueshtiagh, K. Kurose, L. Mu, I. Ueno

Hypothesis: Horseshoe vortices are known to emerge around large-scale obstacles, such as bridge pillars, due to an inertia-driven adverse pressure gradient forming on the upstream-side of the obstacle. We contend that a similar flow structure can arise in thin-film Stokes flow around micro-…

Positional and Rotational Molecular Degrees of Freedom at a Roughened Metal–Organic Interface: The Copper–Fullerene System and Its Multiple Structural Phases

María Alfonso Moro, Y. J. Dappe, Sylvie Godey, Thierry Melin, César González, Valérie Guisset, Philippe David, Benjamin Canals, N. Rougemaille, Johann Coraux

The hybrid metal−organic interaction that molecular monolayers experience when deposited on metallic substrates can compete with intermolecular interactions and produce a variety of on-surface orders. The variety is already important when the molecule/substrate interface remains atomically flat.…

Efficient Co/Pt THz spintronic emitter with tunable polarization

A. Buryakov, A. Gorbatova, P. Avdeev, E. Lebedeva, K. Brekhov, A. Ovchinnikov, N. Gusev, E. Karashtin, M. Sapozhnikov, E. Mishina, N. Tiercelin, V.L. Preobrazhensky

We report on the design of a spintronic emitter based on the Pt(3 nm)/Co(3 nm) structure, which enables the control over terahertz radiation polarization. Utilizing the field-induced magnetization rotation that takes place at low magnetic fields of up to 250 Oe at room temperature, we have achieved…

Functionalization of Carbon Surfaces Using the Copper-Catalyzed Diels–Alder Reaction

Denis Ari, Jean-Francois Bergamini, Teresa Rodrigues, Wolfgang Knoll, Charles Cougnon, Essraa Ahmed, Paulius Pobedinskas, Ken Haenen, Nicolas Nuns, Rabah Boukherroub, Sabine Szunerits, Yann R. Leroux

We propose here a new method to functionalize carbon materials via a catalyzed Diels–Alder reaction. In a Diels–Alder reaction, carbon materials can be used as a diene or a dienophile. Here, carbon materials are used as dienes and alkyne-terminated derivatives as dienophiles. Different carbon…
