Paper on mean free paths published

Pei’s paper with Zhe Wang from John Perepezko’s group on the elastic and inelastic mean free paths of various metallic glasses has be published. This is a topic we’ve studied before, but the new work provides an analytical expression for the elastic mean free path that is validated against glasses with a wide range of atomic numbers. Therefore, it can be applied to predict reliably the elastic mean free path for new alloy compositions.
