Homework Statement
Calculate dhkl and vc for the (111) direction of germanium.
Homework Equations
dhkl=a/sqrt(h2+k2+l2)
vc=unit cell volume=a1dot(a2xa3)
or
vc=structure form factor/density
The Attempt at a Solution
dhkl=a/sqrt(3)
I know how to solve this, I've just forgotten whether a refers to the lattice parameter (5.658 angstroms) or the atomic radius (1.52 angstroms).
for calculating the unit cell volume, I'm a little bit more lost. Could I just take the lattice parameter and cube it, since it's the side length of the unit cell? Thanks in advance.
