Abstract/Summary:


We introduce our multidisciplinary scientific approach, “multicrystalline informatics”. The fundamental idea is to integrate data science with experimental science, theory, and computation in order to enable a paradigm shift in development of materials. Especially, we apply this methodology to realize ideal block-cast silicon by clarifying structural and electrical properties of crystal defects and controlling mechanisms in complicated multicrystalline silicon. The usefulness of multicrystalline informatics is shown by various aspects including analysis of nucleation sites using weighted Voronoi diagram and 3D visualization of generation, propagation, and annihilation of crystal defects.
