Research Abstract

In this study, I developed the criterion to describe the mechanical factures as well as functional instabilities of atomic components. We validated the proposed method as criterion by applying the method to ferroelectric and magnetic systems. In addition, the method describes the origin of fractures and functional instabilities in the atomic components. I further elucidated the multi-physics properties (the coupling effect between mechanical deformation and functionalities) in nano-structured materials.
