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…

The Influence of Microstructure on the Passive Layer Chemistry and Corrosion Resistance for Some Titanium-Based Alloys

Nader El-Bagoury, Sameh Ahmed, Ola Ahmed Abu Ali, Shimaa El-Hadad, Ahmed Fallatah, G. Mersal, Mohamed Ibrahim, Joanna Wysocka, Jacek Ryl, Rabah Boukherroub, Mohammed A. Amin

The effect of microstructure and chemistry on the kinetics of passive layer growth and passivity breakdown of some Ti-based alloys, namely Ti-6Al-4V, Ti-6Al-7Nb and TC21 alloys, was studied. The rate of pitting corrosion was evaluated using cyclic polarization measurements. Chronoamperometry was…

Chapter 3 - Magnon mono-mode circuits: serial loop structures

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

In this chapter and in the frame of long-wavelength Heisenberg model, simple magnonic mono-mode circuits are designed to obtain transmission stop (pass) bands where the propagation of spin waves is forbidden (allowed). These simple devices are composed of infinite one-dimensional mono-mode…

Buffer breakdown in GaN-on-Si HEMTs: A comprehensive study based on a sequential growth experiment

Matteo Borga, Matteo Meneghini, Davide Benazzi, Eleonora Canato, Roland Püsche, Joff Derluyn, Idriss Abid, F Medjdoub, Gaudenzio Meneghesso, Enrico Zanoni

The aim of this work is to investigate the breakdown mechanisms of the layers constituting the vertical buffer of GaN-on-Si HEMTs; in addition, for the first time we demonstrate that the breakdown field of the AlN nucleation layer grown on a silicon substrate is equal to 3.2 MV/cm and evaluate its…
