Hi Prof. Akhmerov,

Sorry I made a mistake in the units of 'I'. Isn't 'I' here the probability current and not the charge current? We would just have to multiply 'I' by e to get the charge current, right?

Thanks,

Harshad

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,AntonOn 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 toHow would I calculate the velocity of the mode, if the modes are normalized to carry unit current?Thanks,Harshad
