Atomic-level defect structure design

The properties of a solid material determine by its crystal structure, which is the arrangement of its constituent atoms. All solid materials have thermodynamically spontaneous defects above 0 K. Defects formed in this way have a significant impact on the flow of electrons and phonons moving along the lattice structure. The properties of solid materials vary greatly depending on the type or degree of defect structure that exists inside the material. We aim to design the microstructure of materials by strategically forming defect structures at the atomic/nano level and achieve performance that greatly exceeds the limits of conventional physical laws. 

Utilizing atomic-level observation equipment such as APT (Atom Probe Tomography) and STEM (Scanning Transmission Electron Microscopy), we clarify the role of defects and validate the rationale behind our defect designing.
