Practical meaning of the 'CELL' object?
« on: June 20, 2020, 13:51 »
Hi QATK community!

I have a trivial question: what is in practical terms the meaning of the cell (continuous white lines in the attachment) ? Is related to the basic unitary cell (crystallography) or more in general it represents the simulation domain where the calculator performs its analysis?

I mean: if I have to simulate for e.g. a FET I have to include in the cell all the objects that influence the transport (like in the attachment: gate and electrodes) or I can for example leave out the gate terminal? And what changes in the two different cases from a computational time standpoint and in the resulted IV curve?

Thank you for your kind attention

The below link shows the device configuration and pn junction. In the device calculation, you can implement the simulation domain in the central region.
