Here is a new twist on graphite! This is fluorinated graphite. The fluorination partially disrupts the graphene sheet; however, the individual fluorine atoms can be detected by our TEM (see arrow) . Since fluorine is the most electronegative element, electrons interacting with it are readily scattered, leaving a "black hole" type of space where the fluorine atom resides. This work is being undertaken in collaboration with Professor James Haw of Texas A and M University.
