The intrinsic electrical conductivity cr of a semiconductor can be approximated by: where is measured in

The intrinsic electrical conductivity cr of a semiconductor can be approximated by:

where σ is measured in („¦-m)-1, Eg is the band gap energy, k is Boltzmann's constant (8.62 x I0-5 ev/K), and T is temperature in kelvins. For Germanium, C = 13.83 and Eg = 0.67 ev. Write a program in a script file that calculates the intrinsic electrical conductivity for Germanium for various temperatures. The values of the temperature should be read from an xls spreadsheet using the xlsread command. The output should be presented as a table where the first column is the temperature and the second column is the intrinsic electrical conductivity. Use the following values for temperature: 400, 435, 475, 500, 520, and 545 K.
