[16a-Z32-6] Correlation between thermal conductivity and persistent homology in amorphous Si
Keywords:Amorphous Si, thermal conductivity, persistent homology
The decrease of lattice thermal conductivity in amorphous materials is originated from the scattering of phonons by structural disorders. However, it has been difficult to discuss the relationship between structural properties and thermal conductivity. In this study, we applied the persistent homology group, which is one of the techniques to extract topology in various numerical data, to investigate whether there is a correlation between topological information and thermal conductivity in amorphous Si.
