Q2 (35 points) Consider the step potential function shown below. Assume that a flux of electrons has energy E and it is incident on a potential barrier of height VO with E > VO. The electrons are traveling in the x direction and they are originated from x=-o. i. (15 pts) Find the transmission coefficient between regions I and II. ii. ii.
