## Description

- description: Stacking monolayers of transition metal dichalcogenides (TMDs) is a
    very effective way to engineer their properties, and has led to the discovery
    of a plethora of new exotic phenomena, driven by the formation of a moir ́e pattern
    which can be probed by the interlayer optical transition. Due to the atomic thickness
    and high surface to volume ratio of such heterostructures, it is expected that
    the interfaces play a crucial role. Fluctuations in the interlayer distance can
    affect the moir ́e potential, and hence the interlayer transition. Therefore,
    to access the intrinsic properties of the TMD stack, it is essential to obtain
    clean and uniform interfaces between the layers. In this work, we show that these
    can be provided by ironing with the tip of an atomic force microscope (AFM). Such
    a post-stacking procedure dramatically improve the structural homogeneity of the
    heterostructure, which is reflected in the interlayer exciton optical response.
    We show that ironing improves the layer coupling, enhancing moir ́e effects and
    reducing disorder in the structure. This is vital for the investigation of TMD
    heterostructure physics, which currently suffers from low reproducibility and
    inconsistent results.
