a A beam of identical electrons of energy E= 9 eV is incident upon a square potential barrier of height U. = 6.5 eV, when E > U.. U(x) 1 2 3 E U. X a = The wave function at region 1 (x < 0): V1(x) = exp(ikıx) + B · exp(-ikıx) and after the barrier region 3 (x > L) the wave function is 13(x) exp(ik3x) a. What is the magnitude of the constant B? 0.4. b. What is the minimal value of a (which is not zero) for which there will be full reflection? (Give answer in nanometer)
