Hello Expert,

Could anyone please provide guidance on the recommended procedure for obtaining the current-voltage (I-V) curve in the context of quantum transport calculations? Specifically, I would like to understand if it is necessary to calculate the transmission spectra (at zero or finite bias) beforehand and subsequently utilize the .hdf5 file containing the transmission data for the construction of the I-V curve or we directly calculate I-V curve.

Your expertise in this matter would be greatly appreciated.

Thank you
