Fig.1From: Molecular Dynamics Study on Tip-Based Nanomachining: A Reviewa Microstructure of single crystal Cu. b Microstructure of nanopolycrystalline. c Microstructure of NT polycrystalline. Atoms are colored according to CNA values, as green and white stand for FCC and defect atoms [25]. d The equilibrated united-atom model of amorphous PE, the model was colored by different molecular chains [26]Back to article page
