Abstract
Molecular-dynamics simulations have been used to identify two cooperative atom-ejection mechanisms which increase sputtering yield. Their effects are analogous to the ‘‘thermal spike,’’ ‘‘shock wave,’’ and ‘‘reduced binding energy’’ sputtering mechanisms. They are examples of nonlinear, many-body, effects in cascades which go beyond collisions between randomly moving particles.Keywords
