Moiré Superlattices Moiré superlattices produced through artificial stacking are often quite challenging to characterize noninvasively. In article number 2008333, Kai‐Qiang Lin, Christian Schüller, and co‐workers present a hyperspectral Raman imaging method to achieve large‐scale mapping of moiré superlattices. The method is based on the finding that both interlayer‐breathing mode and moiré phonons are highly susceptible to the moiré period.
