Title: Calculating and plot dI/dV
Post by: Aadhityan on September 22, 2020, 08:54

How to calculate the dI/dV using scripts? I can get it from IV characteristic tool in ATK.  Since, I have to plot many files, I would be like to calculate  using scripts. I have scripts to plot current from transmission spectrum. Now I want know how to add dI/dV in it.

I have searched for it(dI/dV analysis using script) in ATK. But I didn't get till now.

Thanks...

Use the conductance() query method on the TransmissionSpectrum (https://docs.quantumatk.com/manual/Types/TransmissionSpectrum/TransmissionSpectrum.html)

Dear Anders Blom,
Thanks...

Whether this conductance value(dI/dV) and G are same?

Suppose if I give

 a=conductance (electrode_voltages=0.1 , electrode_temperatures=300)
print a

Will it(print a) give dI/dV value as in additional plot of IV curve plot?

Thanks

This method will just return dI/dV for the given transmission spectrum. You will have to collect the values and print them as a function of the bias yourself.
