Id vs Vg curve

[David1986]

Hi,
I want to plot Id-Vg curve for my transistors but I do not know  how to write python code for drain current vs gate voltage, please give me sample code to learn that, I really need that soon, I sent to you  my code for Id-Vd in attachment file
thank you

Hi,

check this tutorial (and try to reproduce it):

http://docs.quantumwise.com/tutorials/graphene_nanoribbon_device/graphene_nanoribbon_device.html#graphene-nanoribbon-device

in the tutorial you can find the script to plot the conductance as a function of gate voltage, which is a good starting point for the I_D-V_G gate (you just have to plot the current instead of the conductance on the Y axis).

Regards,
Daniele
