plot the fermi distribution function at 200,300 and 400k(all on grah) and discuss the results in comparison to question 4.

these webs may help to plot the Fermi Function

Also I attached answer of Q4 to comparison

NOTE, I would like use excel or Igor pro to plot

#### Solution Preview

Dear Student,

I am sending you plotted graphs of the Fermi distribution function at temperature 200 K, 300 K and 400 K.

Please if you have any questions, do not hesitate to ask me.

You calculated concentrations of the free holes for temperatures:

Clearly, concentration of the holes is increasing as the temperature is rising.
We have an example of p-type semiconductor where the charge carriers are holes. When we add some acceptor atom, the Fermi level will have lower energy with respect to the Fermi level of intrinsic semiconductor; it will be closer ...

#### Solution Summary

The problem was to plot Fermi distribution function for three different temperatures on one graph in Excel.
