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 On Mon, Jan 23, 2017 at 3:49 PM, Harshad Sahasrabudhe <hsahasra@purdue.edu> wrote:
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, Harshad
