Question details

3.15 Tunneling Consider the phenomenon of tunneling through a potential energy barrier of height Vo and width a, as shown in Figure 3.16. What is the probability that the electron will be reflected? Given the transmission coefficient T, can you find the reflection coefficient R? What happens to R as a or Vo or both become very large? a. b. Fora wide barrier (aa » 1), show that To can at most be 4 and that To -4 when E-Vo
