Here we report the atomic structure of the amorphous shear bands in carbide characterized by state-of-the-art aberration-corrected transmission microscopy. Distorted icosahedra, displaced from the crystalline matrix, were observed in nano-sized amorphous bands that produce dislocation-like local shear ...

金刚石分子动力学模拟The structure and lattice damage induced by four boron (B) atoms and eight nitrogen (N) atoms with the energy of 500 eV co-doped into diamond films at room temperature are investigated by molecular dynamics simulation based on Tersoff empirical potential. The results show ...
Here we report the atomic structure of the amorphous shear bands in boron carbide characterized by state-of-the-art aberration-corrected transmission electron microscopy. Distorted icosahedra, displaced from the crystalline matrix, were observed in nano-sized amorphous bands that produce dislocation-like ...
orsp3orbitals, using the singlesorbital with all threeporbitals. Thesp2orbitals of boron tend to be flat trigonal shape, that is, the bonds are at 120 degrees from each other in a flat circle around the boron atom in the center. The Lewis structure of boron is any of the shapes below....
