Molecules intercalating two-dimensional materials form complex structures that have been characterized primarily by spatially averaged techniques. In this work, we use aberration-corrected scanning transmission electron microscopy and density-functional-theory (DFT) calculations to study the atomic structure of bilayer graphene (BLG) and few-layer graphene (FLG) intercalated with FeC l 3 . In BLG, we discover two distinct intercalated structures that we identify as monolayer FeC l 3 and monolayer FeC l 2 . The two structures are separated by atomically sharp boundaries and induce large free-carrier densities on the order of 10 13 c m - 2 in the graphene layers. In FLG, we observe multiple FeC l 3 layers stacked in a variety of possible configurations with respect to one another. Lastly, we find that the microscope's electron beam can convert the FeC l 3 monolayer into FeOCl monolayers in a rectangular lattice. These results reveal the need for a combination of atomically resolved microscopy, spectroscopy, and DFT calculations to identify intercalated structures and study their properties.
