Abstract

Two-dimensional (2D) materials of van der Waals layered crystals, such as graphene and metal dichalcogenides nanosheets, have been used to support the deposition of inorganic nanostructures with controlled orientation and surface alignment via epitaxial growth. Recently, high-quality semiconducting molecular crystals have also been deposited on graphene or hexagonal boron nitride for fabrication of electronic devices with good performance. In this perspective, some examples of deposition of molecular crystals on 2D materials are provided, and challenges and future direction in this field are also discussed.
