WebMar 1, 2024 · Note that the etch rate curve for the <0 1 -1 0> (θ = 30°) crystallographic zone is the same as for the <-1 1 0 0> (θ = 90°) crystallographic zone while similar relations can be pointed out for other cases. Here, the curves start at ϕ = 0 (equator), go through ϕ = 90° (north pole), and finally reach ϕ = 180° (equator). WebChapter 4-5 TEM Crystallography and Diffraction

The translational invariance of a crystal lattice is described by a set of unit cell, direct lattice basis vectors (contravariant or polar) called a, b, and c, or equivalently by the lattice parameters, i.e. the magnitudes of the vectors, called a, b and c, and the angles between them, called α (between b and c), β (between c and a), and γ (between a and b). Direct lattice vectors have components measured in distance units, like meters (m) or angstroms (Å). http://www.clay.uga.edu/courses/8550/millerindices.html bizarre other term https://antonkmakeup.com
