CNRS Images Report - The sculptors of the nanoworld

To sculpt matter at the nanometre scale, where every speck of dust or tiny vibration can compromise their work, physicists need laboratories protected from any disturbances. This report from the Centre for Nanoscience and Nanotechnology shows how scientists use …

Electrical and ion beam analyses of yttrium and yttrium-titanium getter thin films oxidation

Yttrium, titanium, and yttrium-titanium getter thin films were elaborated on silicon by coevaporation in ultrahigh vacuum. Y-Ti films exhibit nanometric crystallites size (18–35 nm) leading to a very high grain boundary density, which is a favorable microstructure for activation …

Discovering the origins of the universe with the QUBIC telescope

QUBIC (QU Bolometric Interferometer for Cosmology) is a cosmology experiment designed to study the so-called inflation period, a period during which the Universe expanded extremely rapidly immediately after the Big-Bang. The characterization of the inflation will be done …
