WebThe chemical potential at T = 0 is called the Fermi energy ε F . All electron states with lower energies are occupied, and all the states with higher energies are empty. In the reciprocal space, the occupied k -states form a circle (in 1D it is a line and in 3D a sphere). WebOkay, so using equation 10 47 for the firming direct distribution, we have that the fermi energy is 3.15 electron volts for sodium. Yeah, Katie is at 293 degrees kelvin, zero point 0 to 5 to electron volts. So D N over V is equal to a pie square to EMC squared to the three house over. Hc cube times. Eat one half T T E over.
