Chapter 6, Problem 40E

(a)

To determine

The two values of the width of the separation between the two barriers; also in terms of the wavelength of the wave function; whether the term is resonant tunneling appropriate.

(b)

To determine

To show: The condition has no solution for zero separation between the two barriers and the reason why.

(c)

To determine

Whether the idea of adding second is a good solution or not.

Suppose that an STM scans a surface at a distance of a = 1.500 nm.   Take the height of the potential energy barrier to be U0 − E = 1.70 eV.   If the distance between the surface and the STM tip decreases by (5.68x10^0)% estimate the percentage change in the tunneling current.  (Here is how you should enter your answer: if the change is 5% write 5.00 and if 20.7% write 20.7 and so on)
Suppose that ak > 0 for all k e N and E ak < 0. For each of the following, prove that the given series converges. ak ( a ) ΣΕΙ 1+ k3ak (b) Lk=1 1+ ak Vak (c) Ek=1 k < 0o.
