Quantum Conductance from ATK
« on: March 28, 2013, 14:15 »
Dear Sir,

Is there a way to plot the quantum conductance G/G0 with ATK.

I have a CNT FET for which I want to plot G/G0 vs Vg. Can it be done with ATK?

You can ask a transmission spectrum for the differential conductance, like
Code: python
t=TransmissionSpectrum(...)
G=t.conductance()
print G
See http://quantumwise.com/documents/manuals/latest/ReferenceManual/index.html/ref.transmissionspectrum.html G is computed in units of G0. So all you need is to compute the transmission spectrum for many different Vg and plot G as a function of Vg.
