I've been trying to figure out the volume of an element in k-space (free electron gas in a crystal lattice).
In deriving the density of states, dn/dE = dn/dk . dk/dE. My dn = 4pi(k^2).dk / V, where V is the volume of an element in k-space.
I came across the spurious, Dk.Dx ~ 2pi (an uncertainty principle relation), where V was said to be (2pi)^3, but that UP doesn't make sense to me.
Could someone shed some light on this?
The ever so grateful MJ...
