a) For the given parameters, explicitly construct and a(x) and b(x) for the Kronig- Penney model. Plot * over 2 periods of the potential.(a+b) = 5 (corresponds to atomic spacing) a=1b=4U0 = 2.4 eVSecond lowest energy band k = /(2(a+b))b)Show that the wavefunction is the same if k = 5/(2(a+b)) (this would be in the second Brillouin zone)c) What is the energy of this state? Is E>U0 or is E
