Hi everyone,
I want to view the electron density (cm-2)in pHEMT structure.
So far what I did was using the menu --> tool/integrate and i got the following pic.



I tried to compare the value with calculation..but I got different answer.

N2deg=((ε_0 ε_S)/(qd^* ))(Vgs -Vt)

Can anyone explain about this..or guide me with this?
Thank you.
 

Hi,

May I ask from which plot you get this electron density pic?
Is it from the sol.str file ? I read recently is to use the "probe" statement, but I don't know how to genertae the code

Thank you
 

Yes, it's from the sol.str file.
If we see the cutline of the structure, we can see this electron concentration.
I never use probe, maybe will try after this.
Thanks for the idea =)
