摘要：

The interface structure of epitaxial polyethylene (PE) crystals was investigated using transmission electron diffraction (TED) and reflection high-energy electron diffraction (RHEED). The crystals were grown on highly oriented pyrolytic graphite (HOPG). The epitaxial growth of PE crystals on MoS2 was also investigated using the results of HOPG. It was found that PE crystallization on HOPG was epitaxial and that the monoclinic, not the orthorhombic, phase was formed at the interface. The monoclinic form was found to be stabilized at the interface due to the energy gain related to the matching of the crystalline lattices.
