Using a computer program in excel plot the electron concentration of silicon doped with 1×1013 cm-3 phosphorus as a function of temperature. Use a temperature range from 300K to 800K. Assume that Nc, Nv, and Eg are temperature-independent, and that they have values of 3.2 × 1019 cm-3, 1.8 × 1019 cm-3 , and 1.12eV respectively. Additionally, use a log scale for the y-axis. How is the electron concentration at 300 K different from electron concentration at 800 K.
