Thermal diffusion in different structures (IMAGE) Science China Press Caption (a) Homogeneous structure with isotropic diffusion. (b) Temperature distribution of (a) at a specific moment. (c) and (d) Insulator-conductor-insulator (ICI) structure with anisotropic diffusion in yellow strips (high thermal conductivity) and isotropic diffusion in green areas (low thermal conductivity).
