Quantum tunneling and corresponding transmission graph

Nov 2019

I am having trouble with understanding how you are supposed to draw corresponding T(E) graphs for V(x) step barrier diagrams, and have a problem which I would appreciated help with to try to understand how you are supposed to solve these exercises.

An even flux of particles is incident from left towards potentials as shown in the 2 diagrams below (attached photo). Discuss what effects that can occur, especially with focus on those energies where something 'new' occurs and how a T(E) sketch would look like and behave corresponding to the diagrams.

Any help is appreciated! Thanks!
