Crystal lattice planes

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. Vectors and planes in a crystal lattice are described by the three-value Miller indexnotation. This syntax uses the indices h, k, and ℓas directional parameters. [4] By definition, the syntax (hkℓ) denotes a plane that intercepts the three points a1/h, a2/k, and a3/ℓ, or some multiple thereof.
