Abstract
The stability and defect formation during the relaxation of zinc oxide nanosheets were studied by molecular dynamics simulations. During the relaxation, an initial flat nanosheet bent to form a curved sheet with approximately a constant radius of curvature. It was found that there was a critical thickness, above which a defect-free nanosheet was formed while below which a defected nanosheet was formed. Two types of defects were found, which resulted from the passage of a perfect dislocation and a partial dislocation, respectively. Energetic analysis based on the continuum framework was also performed and compared favorably with the molecular dynamics simulation results.
