In the third last paragraph of p36, we are told that the Einstein model discussed in this lecture succesfully explains the low heat capacity of diamond - i can't however see how it does, or at least find an explanation anywhere in that lecture.
I follw the argument that at low T, x is large and so the thermal energy is small in comparison to the energy difference between the ground state and the first excited state but how does that help explain the low heat capacity of diamond - surely all we can gather from this is that it's going to be statistically more likely to find particles in the diamond lattice in the ground state?
