Quantum Confined Luminescence in Two Dimensions
Researchers at the Solid State Physics Laboratory (CNRS/Université Paris-Saclay) and their collaborators have developed a new light source: two-dimensional quantum dots created in monolayers of transition metal dichalcogenides. The field …
No need to strike while the iron is… small!
CNRS scientists have studied the evolution of the shape of gold nano-tetrapods and have revealed a two-stage kinetics: the four arms – initially pointed – quickly become blunt, before beginning …
Hund’s coupling mediated multi-channel quantum phase transition of a single magnetic impurity in Fe(Se,Te)
Sub-gap states generated by single spins in a superconductor can be used as building blocks for quantum devices. Physicists at the Laboratoire physique des solides (CNRS/Université Paris-Saclay) have uncovered that …
Efficient conversion of microwave photons into electrons in a high-impedance quantum circuit
Physicists from the Solid State Physics Laboratory (CNRS/Université Paris-Saclay) have demonstrated that it is possible to efficiently convert a flow of microwave photons into a flow of electrons. This efficient …
Topologically trivial gap-filling in superconducting Fe(Se,Te) by one dimensional defects
Physicists at the Laboratoire physique des solides (CNRS/Université Paris-Saclay) have uncovered that the sub-gap states observed in one-dimensional defects in superconducting Fe(Se,Te) are caused by sub-surface debris, contrary to previous …
