Overlaying two atomic layers with a slight lattice mismatch or at a small rotation angle creates a moire superlattice, which has properties that are markedly modified from (and at times entirely absent in) the 'parent' materials. Moire materials have advanced the study and engineering of strongly correlated phenomena and topological systems in reduced dimensions. Understanding electronic phases like superconductivity necessitates precise control in fabrication, involving the rotational alignment of two atomically thin layers with high angular precision.
Overlaying two atomic layers with a slight lattice mismatch or at a small rotation angle creates a moire superlattice, which has properties that are markedly modified from (and at times entirely absent in) the 'parent' materials. Such moire materials have progressed the study and engineering of strongly correlated phenomena and topological systems in reduced dimensions. The fundamental understanding of the electronic phases, such as superconductivity, requires a precise control of the challenging fabrication process, involving the rotational alignment of two atomically thin layers with an angular precision below 0.1 degrees. Here we review the essential properties of moire materials and discuss their fabrication and physics from a reproducibility perspective.
