this is a part of my code
............................................
# do IDVG characteristic
# ramp gate voltage
log outf=tfeyproject2.log
solve vgate1=0 vstep=-0.3 name=gate1 vfinal=-3
save outf=tfeyproject_0.str
#Section 8: Reading the results
tonyplot tfeyproject2.log
extract init inf="tfeyproject2.log"
extract name="psubvt" 1.0/slope(maxslope(curve(abs(v."gate1"),log10(abs(i."drain")))))
tonyplot3d tfeyproject_0.str -set tfeyproject_3.set
quit...........
It shows id vs vg graph.But it cannot find tfeyproject2.log and shows no initialisation is performed.
This is not complete answer but some checks for you.
For simulation up to -3 V on gate, your vstep value of -0.3 V is quite large for quasistatic semiclassical simulation. You should make vstep = -0.01 V. Why the dataset is not recorded in logfile could be due to to the reason that check your directory where ATLAS core simulation is being performed and I do not know whether log outf command can be shifted after the solve command or after save outf command. Tunnel FET has well defined subthreshold slope formula given by Professor Ionescu. In fact Professor Ionescu has published a paper on tunnel FET copyrighted by Silvaco. For extracting slope using extract command, you can use this formula quoted in literature.

Thank you for help Sir. I simulated the following GISTFET. How can i obtain the energy band diagram?
