Massless Dirac fermions in III-V semiconductor quantum wells

Sergey S. Krishtopenko, W. Desrat, K. Spirin, C. Consejo, S. Ruffenach, F. Gonzalez-Posada, Benoit Jouault, W. Knap, K. Maremyanin, V. Gavrilenko, G. Boissier, J. Torres, M. Zaknoune, E. Tournié, F. Teppe

We report on the clear evidence of massless Dirac fermions in two-dimensional system based on III-V semiconductors. Using a gated Hall bar made on a three-layer InAs/GaSb/InAs quantum well, we restore the Landau level fan chart by magnetotransport and unequivocally demonstrate a gapless state in…

Thermal Stability of Oleate‐Stabilized Gd2O2S Nanoplates in Inert and Oxidizing Atmospheres

Clément Larquet, D. Hourlier, Anh-Minh Nguyen, Almudena Torres-Pardo, Andrea Gauzzi, Clément Sanchez, Sophie Carenco

Capping ligands play an important role in the chemistry of nanoparticles synthesized with organic surfactants. This is relevant to a number of device applications where heating may cause major modifications of crystalline nanoparticles including amorphization, surface rearrangements or sintering.…

Chapter 6 - One-dimensional magnonic crystals

L. Dobrzynski, Abdellatif Akjouj, Housni Al-Wahsh, Bahram Djafari-Rouhani

This chapter presents examples of bulk and surface magnons of one-dimensional magnonic crystals, called also superlattices. The such man-made crystals considered here are grown out of semiinfinite stacks of two and also three different ferromagnetic slabs. Each slab is modeled by a simple cubic…

Impact of Measurement Methods over the Characterization of Transient Electromagnetic (EM) Signals above 2 GHz in a Railway Environment

Grecia Romero, Virginie Deniau, Eric Pierre Simon

In order to offer on-board Internet access on trains a Wi-Fi and LTE connection are required. These communicationsystems have to take into account electromagnetic (EM) interferences present in the railway environment in the 2 GHz frequency band since this is a frequency band in which LTE and Wi-Fi…

Polarization-dependent and Valley-protected Lamb Waves in Asymmetric Pillared Phononic Crystals

Wei Wang, Bernard Bonello, Bahram Djafari-Rouhani, Yan Pennec

We present the realization of the topological valley-protected zero-order antisymmetric (A 0) or symmetric (S 0) and zero-order shear-horizontal (SH 0) Lamb waves at different domain walls based on topologically distinct asymmetric double-sided pillared phononic crystals. The elastic periodic…

Design of a four-branch optical power splitter based on gallium-nitride using rectangular waveguide coupling for telecommunication links

Retno Wigajatri Purnamaningsih, Nji Raden Poespawati, El Hadj Dogheche

This paper reports design of a simple four-branch optical power splitter using five parallel rectangular waveguides coupling in a gallium-nitride (GaN) semiconductor/sapphire for telecommunication links. The optimisation was conducted using the 3D FD-BPM method for long wavelength optical…

Evaluation of the hydrophobic properties of latex microspheres and <em>Bacillus</em> spores. Influence of the particle size on the data obtained by the MATH method (microbial adhesion to hydrocarbons)

Christine Faille, Christelle Lemy, Audrey Allion-Maurer, Farzam Zoueshtiagh

The current experimental study investigates the influence of latex microsphere particles' size on the assessment of their hydrophilic/hydrophobic character, using the method known as “Microbial Adhesion to Hydrocarbons” (MATH). Since bacteria surfaces often change according to the environment…
