Dear all,when I compute the transmissionnn spectrum of an metallic carbon nanotube I get the transmission spectrum, where the values are integers of the quantum of conductance. If I try the same for a semiconducting CNT all the points are lower than 4*10^-3. Shouldn't there be also such plateaus multiple of G_0 but across the band gap there should be a zero line?
I attached an example plot. The bandgap is between +/- 0.4 eV, so that seems to work.
What could be wrong here? Best Regards, Jan
