# Potential Barrier Question

Not what you're looking for?

Consider the potential barrier

v(x) = + Vo, |x| < a

0, |x| > a

Solve for the transmission T and the absolute square |T|^2 for both cases E < Vo & E > Vo. Express the answer as |T|^2(x), where x = (2mEa^2)/h^2 = 1.

Plot |T|^2(x) for both E <Vo & E > V.

*Note: Please plot both cases on the same graph.

The way to solve this problem is writing the wave function in each region in the form Aexp(ikx)+A'exp(-ikx)

Then we have to satisfy 4 continuity conditions:

The functions and ...
