Dear Hardshad,

I might be missing some factors here, but the unit of current is elementary charge / unit of time. The unit of time is hbar / unit of energy that you used in defining your tight-binding model.

Best,
Anton

Hi,

I was wondering what units would the wavefunction obtained from Kwant have?  I was thinking they would have the units 1/sqrt(nm.eV) (since my energies are in eV and lengths are in nm) as the modes are normalized according to

How would I calculate the velocity of the mode, if the modes are normalized to carry unit current?

Thanks,
