4.8 Debye crystal. A crystal has a Debye velocity of 5000 ms . ms', and a Deb)c temperature of 500 K. For T 300 K, use matlab (a) Plot the Bose-Einstein distribution as a function of , (b) Plot the density of states as a function o using the Debyeim (c) Plot fD as a function of frequency u. (d) Plot ha p as a function of . (e) Compute the specific heat of the crystal as a function o e model.
