Doolittle opinions and comments: I highlighted in yellow some comments I found interesting. Many I agreed with, many I did not. Highlights are not "endorsements of opinions" only "points of interest in an otherwise lengthy and often repetitive discussion.
Homework 4 A silicon pn diode maintained at 300K has a doping of N a =3x1018 cm3 and N d =1.0x1016 cm3 and mobilities in the two regions of n =1000 cm2/VSec, p =200 cm2/VSec, minority carrier lifetimes in the two regions of n =10 S p =1.2 S. 1) What
ECE 3040 Homework 3
The goal of this homework is to design a photocell (also known as a photoelectric cell or photoelectric resistor) that will respond to light and change its resistance. This device may be used in a later homework problem. The photocell
ECE 3040 Homework 2 1) Purpose: Understanding what the fermidistribution function is telling us. The fermidistribution function depicted in Figure 2.15 describes the probability that a state is occupied at a given energy. Plot the probability that a sta
ECE 3040 Homework 1 1) Given the IVIV compound semiconductor SixGe1x (assume that covalent bonds exist although strictly speaking this is not entirely true) and that energy bandgaps and lattice constants scale linearly, a) What is the lattice constant a
