Prob. 5. Using graphs and calculations to determine bandgap energy The graph below is a plot of intrinsic carrier concentration versus inverse temperature for 3 different semiconductors. Use the equation below combined with data points taken from the graph to determine the energy band gap for Silicon and GaAs. Assume that Nc and Ny do not vary with temperature. Hint: Set up a ratio of the equation using data points from the graph. -E9/2KT ni = N N, e 1019 LL 1018 1017 1076 1015 Ge 1024 1013 Intrinsic Carrier Density , (cm) 102 MITTITT Si 1011 TTT 1010 TUL 10 108 GaAS 107 1003 1 1.5 3 3.5 4 2 2.5 1000/T (K)
