Problem: (a) Derive planar density expressions for (100) in terms of the atomic radius R. (b) Compute linear density values for the plane for aluminum. (c) Consider the (100) plane in FCC: How many atoms are centered on the [100] In FCC?
FREE Expert Solution
(a)
Planar density, PD = number of atoms centered on the plane/ area
For FCC (100):
The number of atoms = (1/4)(4) + 1 = 2
The area of the plane:
A = 8R2
