a bar of n-type germanium and we place an E field going to the right across it and create a pulse of excess minority carriers (holes) in the center of the bar at time t=0. In other words we are performing the Haynes Shockley Experiment on the bar :
a. Which way does the group of holes move and what is driving them?
b. What 2 thing happen to the holes as the move down the bar.
