WebCrystal Planes in Semiconductors Miller Indices All lattice planes and lattice directions are described by a mathematical description known as a Miller Index. This allows the … The defining property of a crystal is its inherent symmetry. Performing certain symmetry operations on the crystal lattice leaves it unchanged. All crystals have translational symmetry in three directions, but some have other symmetry elements as well. For example, rotating the crystal 180° about a certain axis may result in an atomic configuration that is identical to the original configuration; the crystal has twofold rotational symmetry about this axis.

WebSep 8, 2024 · In crystallography, we use Miller indices to specify locations, directions, and planes in a crystal. Standard \(\mathrm{x}-\mathrm{y}-\mathrm{z}\) Cartesian coordinates use a basis consisting of three orthogonal axes in three dimensions with unit length. In Miller index notation, we will rely on the lattice vectors of the unit cell as our basis. Webplane is denoted (Eq. 1). Correspondingly planes of this form ((212), (122), and negative index planes) are denoted by planes of a form: {hkl}, since for cubic crystals implicit in Fig. 1, planes are perpendicular to directions and have equiva-lent indices. It is common practice to denote both planes and directions by (hkl): [hkl] and {hkl}: .
