New Moiré Superconductor

In a recent study published in the journal Nature, Moiré materials made from semiconductor materials have also exhibited superconducting properties.

About the Study

Objective: To explore the reason as to why the semiconductor moiré materials behave differently from graphene in terms of superconductivity to further advance understanding of quantum materials.
Importance: This study created newer avenues to explore superconductivity in semiconductor-based systems and also offered valuable insights into the material’s electronic structure changes when its 2D layers are twisted.

Moiré Superconductor

These materials are characterized by long-range interference patterns (moiré superlattice) arising from the interaction between the layers, which can either be rotationally misaligned or have different atomic constants
Moiré Pattern: It is a result of the interaction between the layers, having different atomic constants or being rotationally misaligned. This pattern modifies the electronic, magnetic, optical, and phononic properties of the heterostructure.
Examples: Transition metal dichalcogenides, Two-dimensional magnets, Twisted graphene, Graphene aligned with hexagonal boron nitride, and Magic-angle twisted bilayer graphene.
Properties: Moiré materials exhibit some interesting phenomena including, Superconductivity, Magnetism, and Quantum anomalous Hall (QAH) effect.
Applications: They have potential applications in nanoelectronics, nano-electronic devices and other fields.
