Reciprocal lattice of simple cubic
WebbFor instance, consider the body-centered cubic lattice as a simple cubic lattice with a basis at $(0,0)$ and $(\frac{a}{2}, \frac{a}{2}, \frac{a}{2})$. It's possible that at some incident angles diffracted waves from these two atoms interfere destructively and you don't see an intensity peak even though you would expect it from a simple cubic reciprocal lattice. Webb26 nov. 2024 · Reciprocal lattice vectors, K, are defined by the following condition: (8.2.1) e i K ⋅ R = 1 where R is a real space lattice vector. Any real lattice vector may be expressed …
