➀ The article discusses the characterization of disordered structures in graphene and monolayer hBN induced by low-energy argon ion irradiation; ➁ It employs automated scanning transmission electron microscopy (STEM) and convolutional neural network analysis; ➂ The study reveals notable differences in the structures of graphene and hBN, with graphene showing amorphization at high defect densities while hBN retains its crystal structure.
