The wave function for an electron and a thin foil with resemble the figure below:
You have found that the probability of tunneling will increase as the total energy of the electron increases. The tunneling probability will also be affected by the properties of the barrier specifically the barrier width and height.
What would you expect to happen to the probability of tunneling as the barrier WIDTH is a) increased and b) decreased?
Check your predictions by clicking on the Barrier Parameters tab, and changing the width to 4 different values. Keep the electron energy constant.
Check your predictions by clicking on the Barrier Parameters tab, and changing the height to 4 different values.
Write a paragraph describing the tunneling probability for various barrier widths and heights, use numerical values where appropriate.
