Electronic Origin of Mechanical Behaviors

Mechanic property is critical for many materials with variety of applications. The mechanic behaviors of solid materials heavily studied since many decades ago with the development of solid mechanics. However, the understanding of mechanic behavior in small scale in still limited due to technique limitation. The recent advances in capturing electronic structures of materials enables the possibility of understand the origin of mechanical behaviors from electronic scale. In this part of research, I am interested in understanding how electronic structure and chemical bonding environment influences the mechanical behaviors of materials.
