Dear Sir,
I am trying to do tutorial for calculating the Charge Transport through
armchair nanoribbons which is given in the link-
http://www.dftbplus.org/fileadmin/DFTB-Plus/public/tutorials/cecamhp/html/transport.html.
The problem is when i was trying to run the code by typing the command "
dftb+ dftb_in.hsd | tee output.log" then it's showing error like this
WARNING!
-> The following 2 node(s) have been ignored by the parser:
(1)
Path: dftb_in/Transport
Line: 5-24 (File: dftb_in.hsd)
(2)
Path: dftb_in/Analysis/TunnelingAndDos
Line: 44-51 (File: dftb_in.hsd)
ERROR!
-> Code halting due to the presence of errors in dftb_in file.The
parameters used in .hsd file is given bellow
please help me how to solve this issue, i will be highly thank full if any
one suggest me to overcome this problems. Here i have write the parameters
for dftb_in.hsd file
Geometry = GenFormat {
<<< 'id.gen'
}
Transport {
Device {
AtomRange = 1 136
}
Contact {
Id = "source"
AtomRange = 137 272
FermiLevel [eV] = -4.7103
potential [eV] = 0.0
}
Contact {
Id = "drain"
AtomRange = 273 408
FermiLevel [eV] = -4.7103
potential [eV] = 0.0
}
Task = ContactHamiltonian{
ContactId = "source"
}
}
Hamiltonian = DFTB {
SCC = No
MaxAngularMomentum = {
C = "p"
H = "s"
}
SlaterKosterFiles = Type2FileNames {
Prefix = "../../../../"
Separator = "-"
Suffix = ".skf"
}
Eigensolver = TransportOnly{}
}
Analysis = {
TunnelingAndDos {
Verbosity = 101
EnergyRange [eV] = -6.5 -3.0
EnergyStep [eV] = 0.01
Region = {
Atoms = 1:136
}
}
}
please help me how to solve this issue, i will be highly thank full if any
one suggest me to overcome this problems.
Thank you
