Fig. 8: Schematic diagram of the cage diffusion mechanism and analysis of cage geometric structures.

a A schematic diagram of the cage diffusion process. b Histogram of the cage volume for the aSiC with different densities and the 6 Å HEGB model. c Histogram of the cage radius for aSiC with different densities and 6 Å HEGB model. The red and blue dashed lines represent mean value and median value, respectively.
