Solid state physics. Consider the following: q p d b d p d b q p d b d p d b q p d b d p d b Indicate: a) a rectangular unit cell b) a primitive unit cell c) the basis of letters associated with lattice points.
Understand the Problem
The question is asking about concepts in solid state physics related to unit cells in a crystalline structure. It requires the identification of a rectangular unit cell, a primitive unit cell, and the basis of letters associated with lattice points based on the given sequence of characters.
Answer
Rectangular unit cell: 'q p d b d p d b'. Primitive unit cell: 'q p d'. Basis: 'q, p, d, b'.
The rectangular unit cell can be chosen to include an entire segment of the repeating pattern, which is 'q p d b d p d b'. The primitive unit cell can be smaller, containing only 'q p d'. The basis includes the sequence assigned to each lattice point within the unit cell, here being 'q, p, d, b'.

The rectangular unit cell can be chosen to include an entire segment of the repeating pattern, which is 'q p d b d p d b'. The primitive unit cell can be smaller, containing only 'q p d'. The basis includes the sequence assigned to each lattice point within the unit cell, here being 'q, p, d, b'.
More Information
In solid state physics, a unit cell is the smallest repeating pattern that can be translated into the entire structure. The primitive unit cell is the smallest possible arrangement that still conveys the symmetry of the lattice and typically contains one lattice point.
Tips
Avoid confusing the primitive unit cell with a rectangular one; the primitive is typically the smallest, simplest version.
