説明:

A graphene/Ge/graphene encapsulated structure was fabricatead. In situ heating TEM revealed that Ge like droplets moved and coalesced with other Ge droplets, indicating that Ge remained as a liquid phase between graphene layers at temperatures higher than the Ge melting point. It was also observed that droplet Ge incorporates the surrounding amorphous Ge as Ge nuclei, thereby increasing its size (domain growth). These results indicated that Ge crystals can be grown at the interface of van der Waals materials, which will be important for future germanene growth at solid interfaces.
