Reduction of helium permeation in microfabricated cells using aluminosilicate glass substrates and Al2O3 coatings

Clément Carlé, Shervin Keshavarzi, Andrei Mursa, Petri Karvinen, Ravinder Kumar Chutani, Sylwester Bargiel, Samuel Queste, Rémy Vicarini, Philippe Abbé, Moustafa Abdel Hafiz, Vincent Maurice, Rodolphe Boudot, Nicolas Passilly

The stability and accuracy of atomic devices can be degraded by the evolution of their cell inner atmosphere. Hence,<br /&gt the undesired entrance or leakage of background or buffer gas, respectively, that can permeate through the cell walls,<br /&gt should be slowed down. In this...

Optimized emitter-base interface cleaning for advanced Heterojunction Bipolar Transistors

E. Brezza, F. Deprat, C. de Buttet, A. Gauthier, M. Gregoire, D. Guiheux, V. Guyader, M. Juhel, I. Berbezier, E. Assaf, L. Favre, P. Chevalier, Christophe Gaquière, N. Defrance

A B S T R A C T Heterojunction Bipolar Transistors needed for high-frequency applications require precise dopant control. Insitu doped epitaxies used during device fabrication rely on surface preparation to obtain an optimized doping profile. Defects due to imperfect cleaning relates to high...

Mesoscopic Klein-Schwinger effect in graphene

A. Schmitt, P. Vallet, D. Mele, Michael Rosticher, T. Taniguchi, K. Watanabe, E. Bocquillon, G. Fève, Jean-Marc Berroir, Christophe Voisin, J. Cayssol, M. Goerbig, J. Troost, E. Baudin, Bernard Plaçais

Strong electric field annihilation by particle–antiparticle pair creation, also known as the Schwinger effect, is a non-perturbative prediction of quantum electrodynamics. Its experimental demonstration remains elusive, as threshold electric fields are extremely strong and beyond current reach....
