Unravelling stacking order in epitaxial bilayer MX using 4D-STEM with unsupervised learning.

Following an extensive investigation of various monolayer transition metal dichalcogenides (MX), research interest has expanded to include multilayer systems. In bilayer MX, the stacking order strongly impacts the local band structure as it dictates the local confinement and symmetry. Determination of stacking order in multilayer MX domains usually relies on prior knowledge of in-plane orientations of constituent layers.

Superconducting Ferromagnetic Nanodiamond.

Superconductivity and ferromagnetism are two mutually antagonistic states in condensed matter. Research on the interplay between these two competing orderings sheds light not only on the cause of various quantum phenomena in strongly correlated systems but also on the general mechanism of superconductivity. Here we report on the observation of the electronic entanglement between superconducting and ferromagnetic states in hydrogenated boron-doped nanodiamond films, which have a superconducting transition temperature T ∼ 3 K and a Curie temperature T > 400 K.

Thermal and quantum depletion of superconductivity in narrow junctions created by controlled electromigration.

Superconducting nanowires currently attract great interest due to their application in single-photon detectors and quantum-computing circuits. In this context, it is of fundamental importance to understand the detrimental fluctuations of the superconducting order parameter as the wire width shrinks. In this paper, we use controlled electromigration to narrow down aluminium nanoconstrictions.
