ELEG 341 - Solid State Electronics II Fall 2010 Homework #12 - due Wednesday, 1 December 2010, in class 1. Problem 7.21 in chapter 7, p. 394 of Streetman & Banerjee (6th edition). Hint, use the parameters from Section 7.5.2 to the extent possible, and calculate β N . There is no need to provide the “comments” of the later part of the question. 2. Problem 7.24 (endpoints only) in chapter 7, p. 395 of Streetman & Banerjee (6th edition). Note: just calculate V EB , not the injection efficiency. 3. Problem 8.1 (c only) in chapter 8, p. 433 of Streetman & Banerjee (6th edition). Note: pick a material that would absorb light with λ < 0.6 μm, but do not pick a substrate. 4. Problem 8.2 (a only) in chapter 8, p. 433 of Streetman & Banerjee (6th edition).

Unformatted text preview: Hint; consider the velocity of carriers that is produced by the applied voltage, and the resulting transit time of an average electron over the dimensions of the device. 5. Problem 8.8 in chapter 8, p. 433 of Streetman & Banerjee (6th edition). Hint: to calculate V oc , start with the equation for the total current and solve for V when I tot = 0 (i.e. open circuit) Homework assignments will appear on the web at: http://www.ece.udel.edu/~kolodzey/courses/eleg341f10.html Note: On each homework and report submission, please give your name, the due date, assignment number and the course number....
