why the equation density carrier electron vs temprature don't fit with graph of book?
hi,in link https://www.iue.tuwien.ac.at/phd/wittmann/node7.html that it is too there is in yang micro device,there is a graph that can see below:
the equation of carrier is below
our default is NA=0 and we have n-type silicon, when i plot this equation in matlab we don't arrive this graph!!11
why i do wrong?!!!:sad:

the output from matlab is here:clc
clear
Nd=10^16;
Eg=1.4;%ev
K=8.6173324*10^(-5);%ev
m0=9.109*10^-31;
me=1.08*m0;
mh=.56*m0;
h=4.135667662*10^(-15);%ev
y=@ (T) 1/2+1/2*(1+16*(6.28*K*T*(me*mh)^.5*(1/h^2))^3*exp(-Eg/K*T)*1/Nd^2)^.5;
fplot(y,[1,2]);
why i do wrong?!!!:sad:
