Hello Kwant Developers,
1. I am new to Kwant. In tutorial 2.5, it is mentioned that the conductance
unit is [e^2/h] whereas I find some papers using Kwant mentioned as [2e^2/h]
for e.g. https://doi.org/10.1016/j.physleta.2020.126990. Please clarify this.
2. I calculate the energy (unit in eV) from the KPM method and then calculate
the conductance in Kwant. What's the unit for the conductance in my case?
Please find below the code that I used to calculate the conductance.
def dos_eng(model1):
rho = kwant.kpm.SpectralDensity(model1)
eng1, densities = rho.energies, rho.densities
return eng1, densities
def calc_conductance(sys, energies):
# Compute transmission as a function of energy
data = []
for energy in energies:
smatrix = kwant.smatrix(sys, energy)
data.append(smatrix.transmission(1, 0))
return data
Thanking You,
Ajit
