[Kwant] Units of the wavefunction and velocity

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 [image: Inline image 1] How would I calculate the velocity of the mode, if the modes are normalized to carry unit current? Thanks, Harshad
