introduce my name Arjuna Wiwaha
I would like to complain regarding the FEMLAB software Version 2.1 that I have ...
why the tutorial library models of semiconductor diode device
I can not run the command "computing the IV Characteristics''?
this command ==>
for i=1:21
for b=1:9
In(i,b) = posteint(fem,'Dn*ni*nx.*exp(phi).*ux+Dn*ni*ny.*exp(phi).*uy','Bdl',b,'solnum',i);
Ip(i,b) = posteint(fem,'-Dp*ni*nx.*exp(-phi).*vx-Dp*ni*ny.*exp(-phi).*vy','Bdl',b,'solnum',i);
end
end
I0=q*D0*C0*1e-4;
In=In*I0;
Ip=Ip*I0;
figure
semilogy(fem.sol.tlist,abs(In(:,[2 5])+Ip(:,[2,5])),'-x')
axis([0 0.5 1e-12 1e-2]);
ylabel('Current [A/\mum]');
xlabel('Voltage [V]');
title('IV-characteristics');
This command error for computing the IV Characteristics, Hep me pleace !!!
please reply soon!
thank you!
