Improved modified embedded-atom method potentials for gold and silicon
نویسندگان
چکیده
The modified embedded-atom method interatomic potentials for pure gold and pure silicon are improved in their melting point and latent heat predictions, by modifying the multi-body screening function and the equation of state function. The fitting of the new parameters requires rapid calculations of melting point and latent heat, which are enabled by efficient free-energy methods. The results provide the basis for constructing a cross-potential that will be fitted to the binary gold–silicon phase diagram.

A new Embedded Atom Method potential for atomic-scale modeling of metal-silicon systems
A new formulation of EAM potential is developed for the description of interatomic interactions in metal-silicon systems. The potential is based on reformulation of the Embedded Atom Method (EAM) potential for metals and Stillinger – Weber (SW) potential for silicon in a compatible functional form. The potential is parameterized for Au-Si system and tested by comparing the predicted energies an...
متن کاملA gold-silicon potential fitted to the binary phase diagram.
We develop an empirical interatomic potential model for the gold-silicon binary system that is fitted to the experimental phase diagram. The model is constructed on the basis of the modified embedded-atom-method formalism and its binary phase diagram is computed by efficient free energy methods. The eutectic temperature and eutectic composition of the model match well with the experimental valu...

متن کاملMacroscopic measure of the cohesive length scale: Fracture of notched single-crystal silicon
We study atomistically the fracture of single-crystal silicon at atomically sharp notches with opening angles of 0° ~a crack!, 70.53°, 90° and 125.3°. Such notches occur in silicon that has been formed by etching into microelectromechanical structures and tend to be the initiation sites for failure by fracture of these structures. Analogous to the stress intensity factor of traditional linear e...
