WebJan 16, 2024 · The following treatment of the procedure used to assign the Miller Indices is a simplified one and only a cubic crystal system (one having a cubic unit cell with dimensions a x a x a ) will be considered. The procedure is most easily illustrated using an example so we will first consider the following surface/plane: 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.
