Consider the potential well defined by

V(x)= {0 -L/2<x<L/2}

{Vo x>L/2 or x<L/2}

1. For E>Vo (unbound state, find the solutions to the time-independent Schroedinger equation for a particle incident from the left and traveling to the right(Use boundary conditions to evaluate coefficients A-F)

2. Find expressions for the transmission and reflection as a function of energy.

3. Find the necessary conditions for perfect transmission. Interpret this condition on physical grounds (note that k=2pi/gamma, which reflects the wave vector ,k, to the wavelength).

Solutions

Expert Solution

3. Perfect transmittance is when reflectance is zero.

i.e when k1 = k2. Then R = reflectance = 0. And transmittance = 1.
