The emergence of a topological superconducting state in van der Waals heterostructures provides a new platform for exploring novel strategies to control topological superconductors. In particular, impurities in van der Waals heterostructures, generically featuring a moir\u00e9 pattern, can potentially lead to the unique interplay between atomic and moir\u00e9 length scales, a feature absent in generic topological superconductors. Here we address the impact of nonmagnetic impurities on a topological moir\u00e9 superconductor, both in the weak and strong regime, considering both periodic arrays and single impurities in otherwise pristine infinite moir\u00e9 systems. We demonstrate a fine interplay between impurity-induced modes and the moir\u00e9 length, leading to radically different spectral and topological properties depending on the relative impurity location and moir\u00e9 lengths. Our results highlight the key role of impurities in van der Waals heterostructures featuring moir\u00e9 patterns, revealing the key interplay between length and energy scales in artificial moir\u00e9 systems.<\/p>\n
