show work thanks. A 10 eV electron (an electron with a kinetic energy of 10 eV) is incident on a potential-energy barrier that has a height equal to 13 eV and a width equal to 1.0 nm. T = e^-2alpha a alpha > > 1 Use the above equation (35-29) to calculate the order of magnitude of the probability that the electron will tunnel through the barrier. 10 _________ Repeat your calculation for a width of 0.10 nm. 10 _________
