Find the nearest neighbor (center to center) distance for sc, … WebExpert Answer. [20 points] Consider a Body Centered Cubic (BCC) structure (Iron crystal) with lattice constant 'a' and an atom at the center of the unit cell (labeled 'D'). We are looking to find the surface energy of the new surface that is formed after it is sliced at the (111) plane. The (111) plane includes atoms 'A', 'B' and 'C' but does ...

WebCorrect option is A) In bcc unit cell, 1 atom is present at the center of the body and 8 atoms are present at the 8 corners of body. The atom at the center of body contributes fully to the unit cell. The contribution of each corner atom to the unit cell is one eight. Hence, the total number of atoms in the unit cell is 81×8+1=2.

Webunit cell contains an equivalent of four lattice points, compared to two for the BCC lattice, and one for a simple cubic lattice. Both the diamond cubic and zincblende structures have an FCC Bravais lattice with each lattice point associated with two atoms, i.e., basis group, rather than just one as in the simple case.
