The electrons are traveling in the x direction and they are originated from x =--, i. Find the transmission coefficient between regionsl and II ii. Find the reflection coefficient between regions l and II. iii. Assume the electron velocity is 2. x10° cm/s, E = V0 /0.1. Find the probability that there is an electron at the distance a = 2 A'after the barrier.
