attached is the related documents:first,conductance--gatevoltage[-8.0,8.0V]every0.25Va point.
second,conductance--gatevoltage[-0.1,0.1V]every0.02Va point(in order to make sure the problem is not caused by small density of gatevoltage).
third,script to calculate the transmission
forth,gatescan script
