7.7 The measured thermal conductivity of germanium at 300°K is 0.63 W/°K, in a range where acoustic phonon scattering dominates. (a) What fraction of this thermal conductivity is caused by free electrons if the free-electron density is 1017 cm-³ and the electron mobility is 4x 10 cm2/V-sec? (b) What must the concentration of free electrons in germanium at 300°K be in order for the electronic contribution to the thermal conductivity to be equal to the lattice contribution? (c) The thermoelectric power corresponding to (a) is measured to be 0.46 mV/°K. How far below the conduction-band edge does the Fermi level lie?

Q.1. The metals Cu and Pb have diamagnetic susceptibilities -9.63×10-6 and -1.58x10-5, respectively. Furthermore, Pb is a superconductor with T=7.2 K and Bo=800 G. Compare the magnetic energies of Cu and Pb in an external field of 500 G at 7.5 K and 0.1 K; assume the long-wire geometry with the field parallel to the wire. What is the principal difference in the free energy of the Pb sample at the two temperatures and in the presence of the field?
