Stacking faults and partial dislocations in graphene
We investigate two mechanisms of crystallographic slip in graphene, corresponding to glide and shuffle generalized stacking faults (GSF), and compute their -curves using Sandia National Laboratories Large-scale Atomic/Molecular Massively Parallel Simulator (LAMMPS). We find evidence of metastable partial dislocations for the glide GSF only. The computed values of the stable and unstable stackin...
متن کاملStacking Faults in Co-Alloy Longitudinal Media
Stacking faults in CoCrTa/Cr, CoCrPt/NiAl, and CoCrPt/Cr/NiAl films have been studied by electron diffraction. Interfacial lattice match and epitaxial growth play important roles in reducing the stacking fault density. It is found that the bicrystal media has large stacking fault densities. In the unicrystal media case, when good epitaxy between magnetic layer and underlayer cannot be achieved,...
متن کاملOn the energy of terminated stacking faults
The equilibrium of dissociated dislocations is discussed in terms of intrinsic material properties such as the ideal stacking fault energy (ideal SFE) and the stacking fault (SF) strain. The ideal SFE is de® ned as the energy per unit area of an in® nitely extendedSF in an ideal in® nite crystal. The e ective SFE is de® ned as the energy per unit area of a terminated SF. The terminated SF is a...
متن کاملProton Diffusion in Nickel Hydroxide Films
Electrochemical impedance spectroscopy (EIS) was used to measure the solid-state diffusion coefficient of protons in nickel hydroxide films at room temperature as a function of state of charge (SOC). A model for the complex faradaic impedance of the nickel hydroxide active material is presented and used to extract the diffusion coefficient of protons from the EIS data. Impedance data over a ran...
