1) What do you mean by a carrier concentration of metals?
2) Fermi temperature of the metal is 24600k. Compute the Fermi velocity.
3) Determine the value of f(E) for E-EF= 0.01eV at 200K by using Fermi function.
4) Thermal conductivity of copper at 20^{o}C is 390 wm^{-1 }k^{-1} and 5.87x10^{7} mho/m respectively. Compute the Lorentz Number.
5) Derive the mathematical expressions for electrical conductivity and thermal conductivity of the material and therefore get widemann - franz law.
6) Deduce the expression for density of states and based on that compute carrier concentration in metals.
7) prepare down Fermi-Dirac distribution function. Describe how Fermi function differes with temperature. Estimate the Fermi function for energy KT above the fermi energy.
