Calculate the formation entropy for a simple cubic crystal. | ||
Assume that there are two kinds of springs holding the atoms together: Springs between next neighbors, and springs between second next neighbors. | ||
Look at the resonance frequency as a function of the spring constant D (make some assumptions about the spring constant D_{2} of the second-next-neighbor spring in terms of the spring constant D_{1} of the next neighbors). | ||
Calculate the formation entropy first by only considering the D_{1} springs; than consider the D_{2} springs, too. | ||
