Signatures of moir\'e-trapped valley excitons in MoSe$_2$/WSe$_2$ heterobilayers [PDF]
, 2018 The creation of moir\'e patterns in crystalline solids is a powerful approach to manipulate their electronic properties, which are fundamentally influenced by periodic potential landscapes. In 2D materials, a moir\'e pattern with a superlattice potential
