Web21 jul. 2024 · 1 My textbook says the following in a section on Miller indices: Adjacent planes ( h k l) in a simple cubic crystal are spaced a distance d h k l from each other, with d h k l given by: (2.12) d h k l = a h 2 + k 2 + l 2 where a is the lattice constant. Equation 2.12 provides the magnitude of d h k l and follows from simple analytical geometry. WebMiller indices, group of three numbers that indicates the orientation of a plane or set of parallel planes of atoms in a crystal. If each atom in the crystal is represented by a point and these points are connected by lines, the resulting lattice may be divided into a number of identical blocks, or unit cells; the intersecting edges of one of the unit cells defines a …

For the special case of simple cubic crystals, the lattice vectors are orthogonal and of equal length (usually denoted a), as are those of the reciprocal lattice. Thus, in this common case, the Miller indices (hkℓ) and [hkℓ] both simply denote normals/directions in Cartesian coordinates. For cubic crystals with lattice constant a, the spacing d between adjacent (hkℓ) lattice planes is (from above) WebThe Miller indices with non-zero structure factor correspond to “allowed reflections”. The rest are called "systematic absences". A list of these by Miller indices would be infinitely long, but we can write out a partial list of the first few: {110} {200} {202} {222} {400} . . .
