Solution Summary
This problem of determination of the width of the potential barrier is solved using the concept of transmission probability.
Solution Preview
The transmission probability of an electron with energy E through a potential barrier U is given by the relation :
_____
T = e-2{[√2m(U-E)]/ħ} L ................(1)
Where,
T = Transmission probability through the barrier = 10-4
m = Mass of ...
