For an electron of energy 1 eV, estimate the permeability of a one-dimensional rectangular potential barrier with a width of 5 A and a height of 2 eV. What is the transparency coefficient of the barrier? Note. The permeability of a rectangular barrier is the quantity a = , where U0 is the height of the barrier, E is the energy of the incident particle, m is its mass. The barrier transparency coefficient is the square of the ratio of the amplitude of the wave function of the transmitted wave to the amplitude of the wave function of the incident wave.
