Question 1
MatLab Code
clear all;
T =275:1:500;
k = 1.38*10^(-23);
z = 1.609*10^(-19);
ni_si = (9.15*10^(19)).*((T./300).^2).*exp(-0.5928*z./(k.*T));
ni_Ge = (1.76*10^16).*(T.^(3/2)).*exp(-0.392*z./(k.*T));
plot(T,ni_si,'b');

The curves above have been generated by employing the empirical fit relationships in the
equations given. This confirms that the ni versus T curve for both Germanium and silicon can be
generated using the gi...
