A square barrier of height Vo = 5.0 eV and width of a = 1.0nm has a beam of electrons incident on it having kinetic energy E = 4.0 eV. The wave function for x less than or equal to 0 can be written, Psi1 = Aeik1x + Be-ik1x and for the region inside the barrier, the wave function can be written Psi2 = Cek2x + Dek2x. Determine the equations describing the continuity conditions at x=0.
