An unusual form of superconductivity, which could help develop powerful quantum computers, has been found at the interface between two thin films by RIKEN physicists (Nature Communications, « Nonreciprocal charge transport at topological insulator/superconductor interface »).

Scientists have created thin films made from barium zirconium sulfide (BaZrS3) and confirmed that the materials have alluring electronic and optical properties predicted by theorists.

3 Questions à Maryline Nasr, chef de projet CIBOX au sein du Crismat à Caen.
Bonjour Maryline, depuis le mois de Janvier 2020 vous êtes chef de projet du programme CIBOX en partenariat entre le laboratoire CRISMAT et CODEX INTERNATIONAL. Pourriez-vous nous rappeler les principaux enjeux de ce programme ?

Il y a 2 enjeux principaux :

A group of materials scientists at Tokyo Institute of Technology has shown that a palladium-based intermetallic electride, Y3Pd2, can improve the efficiency of carbon-carbon cross-coupling reactions. Their findings point the way to a more sustainable world through catalysis.

Two-dimensional (2D) materials could offer new building blocks for future technologies — but only if scientists can control growth and properties. Strain, caused by “stretching” or “bunching” the atomic structure as a crystal grows, is one way to control these properties.

A special class of materials known as “Weyl semimetals” have unusual physical properties. In these materials, researchers can separate electrons by their “handedness.” That’s whether the electrons’ magnetic moment is in the same direction as the electrons’ movement or the opposite direction.
This results in a host of unique phenomena that researchers can use to turn infrared light into electricity and develop very fast electronic circuits.

Researchers have created a unique device which will unlock the elusive terahertz wavelengths and make revolutionary new technologies possible.

Researchers at Seoul National University and Inha University in South Korea developed photo-sensitive artificial nerves that emulated functions of a retina by using 2-dimensional carbon nitride (C3N4) nanodot materials.

Quantum information technologies need materials that can produce a regular stream of single particles of light (photons). Two-dimensional materials are made of single layers of coordinated atoms.
Recent research has shown that these 2D materials may have potential as light sources that emit light as single photons.
