Hint: assume that the depletion thickness is known and that the depletion edges lie at ±x d0 /2; find n and p in terms of n i and E i at these two points, and thus determine the two values of E i – E F . Find φ from the difference in these. 5. Problem 5.6 in chapter 5, Muller & Kamins, p. 275 in 3rd edition. (Hint: start with Eqn. 5.3.10, and for short base diode, recombination in the bulk can be neglected.) Homework assignments will appear on the web at: http://www.ece.udel.edu/~kolodzey/courses/eleg646s11.html Include your name, due date, assignment number, and course number on each submission....
