WebMiller-Bravais indices are a 4-axis coordinate system for 3-dimensional crystals, based on the unit cell. This coordinate system is based on the 3-axis Miller index, but with an extra axis which is used for hexagonal crystals. The system can indicate directions or planes, and are often written as (hkil). WebDe manera equivalente, (hkℓ) denota un plano que intercepta los tres puntos a 1 / h , a 2 / k y a 3 / ℓ , o algún múltiplo de los mismos.

Web29 jul. 2024 · What is HKL in Miller indices? Equivalently, (hkℓ) denotes a plane that intercepts the three points a 1 /h, a 2 /k, and a 3 /ℓ, or some multiple thereof. That is, the Miller indices are proportional to the inverses of the intercepts of the plane, in the basis of the lattice vectors. How is the interplanar distance is determined in a crystal? Webpoint (hkl) lies exactly on the Ewald sphere. (The way that the reciprocal lattice is defined means that the vector from the origin to the reciprocal lattice point hkl (d*) will be normal to the planes with Miller indices hkl and will have a magnitude 1/d, where d is the interplanar spacing. This is left as an exercise for the student.)
