May 1, 2020 · I saw Theoretical Condensed Matter in your profile; these unanswered or incompletely answered questions may be of interest to you Straightforward formalism to get …

Oct 6, 2015 · When I consider the primitive unit cell of a fcc lattice (red in the image below) the lattice points are only partially part of the primitive unit cell. All in all the primitive unit cell …

Feb 28, 2024 · Physical way? Transform to reciprocal space and see. Intuitive way? Likely your intuition doesn’t work the same way mine does. But note that there are not many lattices to …

The a i a → i are called the lattice vectors and are just there to define the cubic structure. They can be chosen the same for the simple cubic, the bcc and the fcc lattice. What you need are …

Sep 9, 2020 · Take the (111) surface of a fcc lattice: If we have a wave incident on the surface moving in a direction with a projection parallel to the orange line, then in principle we should …

Aug 6, 2024 · I am new to working with 3D lattices and am wondering if there are any well-developed methods for generating all k k -points inside the first Brillouin zone (BZ) of an FCC …

Mar 2, 2016 · In an FCC crystal (let's say an iron crystal) there is a basis which contains four atoms, and the origin of the lattice displacement vectors for those four atoms is the 'lattice …

Mar 26, 2020 · I need help understanding why the step on this Wikipedia page is true. Why does the structure factor of the diamond lattice is the product of the structure factor of a BCC Lattice …
