Scanning tunneling microscopy of defects on graphite. The image was acquired with a sample bias voltage of 100 mV and tunneling current setpoint of 0.7 nA. a The defects (box outline) are monovacancy–hydrogen complexes generated through Ar+ ion bombardment, followed by annealing in a hydrogen environment. These defects modulate the local electronic density of states in their immediate vicinity as shown in the inset. The color bar is normalized intensity. b Extraction and classification of atoms, select edge atoms surrounding a monovacancy–hydrogen complex (e.g., outlined region 1) as being distinct from the rest of the atoms in the system, with different structural classes encoded by a unique color label
