In this video, two VESTA models of cutting planes of monoclinic HfO2 grains are overlaid and moved laterally to each other (other degrees of freedom are not allowed in the present system). The cutting planes are the (-1-1-2) and (-121) planes for the purple (grain 1) and green (grain 2) lattice respectively. Moiré fringes are visible as the move due to the lateral shift of the lattices, also indicated by the red dotted lines. The...
