WebIt is found that the atomic alignment and atomic density on different types of crystal facets of BiVO 4 are different, which results in significant differences in its bandgap, charge lifetime, Raman scattering, and thermal diffusivity. In heat transfer analysis, thermal diffusivity is the thermal conductivity divided by density and specific heat capacity at constant pressure. It measures the rate of transfer of heat of a material from the hot end to the cold end. It has the SI derived unit of m /s. Thermal diffusivity is usually denoted by lowercase alpha (α), but a, h, κ (kappa), K, and D are also used. The formula is:
