We use the notation from the exercise and the solution sheet. We start by considering states with a certain energy E(and corresponding 2= a p 2mE=~ ). In between the delta-barriers, the state is given by a superposition of plane wave states.

WebIn Kronig-Penny model, it is assumed that the potential energy of an electron in a linear array of positive nuclei has the form of a periodic array of square wells (Fig. 5.10). Let the period of the periodic potential be (x + b). For -b < x < 0 the potential energy is V0 while for 0 < x < a the potential energy is zero. The Schrodinger equations for two cases are- If V0 > …
