Infinite and finite potential energy well First consider an infinite one dimensional PE well of width 1 nm. Calculate the energies of the first three levels. Consider a finite PE well with the same width (1 nm). The height of the barrier is 2.0 eV. There are only three energy levels E1 0.23 eV. E2- 0.89 eV, and Es 1.81 eV. Are the finite PE well levels higher or lower than the corresponding infinite well levels? Find the electron penetration depth into the barrier for each of the three energy levels. What is your conclusions?
