Subproject C05 Joining simulation

The objective of subproject is to systematically investigate the bonding between deoxidized joining partners for various bonding processes by means of classical molecular dynamics simulations. It will be clarified how the absence of oxide layers affects the underlying mechanisms that influence the joint quality. This requires an understanding of the atomic bonding mechanisms at the interfaces in silane-doped atmospheres and the fundamental dependence on deoxidation state and temperature.
