Undulation-induced moiré superlattices with 1D polarization domains and 1D flat bands in 2D bilayer semiconductors
Xingfu Li, Sunny Gupta, Boris I. Yakobson
Two-dimensional (2D) materials have a high Föppl-von Kármán number and can be easily bent, much like a paper, making undulations a novel way to design distinct electronic phases. T…
