Web1. Identify the coordinate intercepts of the plane (i.e., the coordinates at which the plane intersects the x, y,andz axes). If plane is parallel to an axis, the intercept is taken as infinity ( ). If the plane passes through the origin, consider an equivalent plane in an adjacent unit cell or select a different origin for the same plane. 2. WebJan 30, 2024 · Crystal planes come from the structures known as crystal lattices. These lattices are three dimensional patterns that consist of symmetrically organized atoms intersecting three sets of parallel planes. These parallel planes are "crystal planes" and are used to determine the shape and structure of the unit cell and crystal lattice. flag with red black white and greenWebThe lattice describes the repeat pattern; for diamond cubic crystals this lattice is "decorated" with a motifof two tetrahedrallybondedatoms in each primitive cell, separated by 1/4of the width of the unit cellin each dimension.[1] flag with red blue and white stars
