Hello siesta users

       Recently, I am calculating the gate-bias modulation effect of
graphene sheet  using transiesta. When I set different external electric
fields perpendicular to the sheet ,  the changes  of currents along the
sheet  are less than 1% with the original current without external electric
field.  I have send my input files to you, would you please help me check
them? I wonder if siesta can  calculate the gate-bias modulation effect of
graphene sheet. Thank you in advance.
