8. Consider a potential barrier defined by 0 I <0 0 < x L U(z)=Uo 0 with Uo= 1.00 eV. An electron with energy E> 1 eV moving in the positive z- direction is incident on this potential. The transmission probability for this situation is given by T: 4(E/U₁) [(E/U₁) − 1] sin² √2m(E- Uo)L/h + 4(E/Uo) [(E/U) − 1] It is found that the reflection probability is zero for E= 1.10 eV and non-zero for smaller incident energies. What is the width of the potential barrier L?
