Abstract
Graphene has been considered as an ideal gas barrier material because of the sp2 carbon network structure. However, chemical vaporized deposition (CVD) graphene developed for large scale applications contains many defects in nanoscale because of mismatched structures at domain boundaries and missing carbon atoms even in single graphene domain. Thus, developing a way to control these defects is critical for gas barrier application using CVD graphene. Here, we report that self-assembled alkane layers could physically block defects in nano size due to their strong van der Waals interactions of alkane molecules. This molecular behavior was confirmed by scanning tunneling microscopy (STM) which can visualize both self-assembled monolayer and graphene under the monolayer at the same time.
