Hello
i have checked the tutorial given on the following page: https://docs.quantumatk.com/tutorials/graphene_nanoribbon_device/graphene_nanoribbon_device.html#graphene-nanoribbon-device
the conductance obtained in the given example changes about 20 times for the gate voltages of 0V and -2V. however, the reference paper given here: https://doi.org/10.1021/nl070133j shows that the conductance changes 2000 times for the gate voltages of 0V and -2V.
What is the source of the big difference between the results given in the reference paper and the tutorial?
thanks.
