= There are N electrons moving one-dimensionally and they encounter a barrier of width a 2.0 angstrom and potential energy V₁ =3.3 eV. a) If each electron carries 3.8 eV of energy before interacting with the barrier and there are N = 3500 electrons, determine how many electrons go to the other region and how many return.
b) For the given energy values and having the possibility to control the width of the barrier. For what values of a do you have the maximum number of electrons passing to the other region? For what values of a do you have the maximum number of electrons returning to the first region? c) If now the same number of electrons with energy 1.8 eV are incident, determine the number of electrons that cross the barrier.
