摘要
<正>In van der Waals heterostructures of atomically thin 2D materials, the inevitable lattice mismatch and twisting betweenthe building blocks always lead to the formation of Moire pattern, which is a periodic spatial pattern of varying atomic registries. Theory has predicted that such a nanoscale moire landscape can endow excitons highly intriguing properties (Science Advances 3, e1701696 (2017)), including their confinement in an array of quantum dot like potential traps with circu-
