Please solve this question completely and in a (correct) way as soon as possible and in its entirety. An accurate solution, without explanation. I just want the mathematical solution (solid state physics) to give you a very good evaluation.
Question One: (10 points) cho nous. * (10 points) TOUWS a) If the average number of phonons of wave vectors k for a bulk crystal is Write down the total thermal energy of the crystal:: crystal of the energy bulk crystal <4k) Phonors. b) Write down the Planck distribution function of phonons of frequency o at thermal Phonons.] of frequency wat thermal equilibri is given by: 4 ilibrium is given by. 4/13 VN De was. c) Write down the density of K wave vectors for a linear lattice of length L and number of PRO 3-10 10 vectors for a linear Lattice atoms N: d) Write down the density of modes D() for a linear lattice of length L and number of re of 0(w) for a linear Lattice of Lenght.
