Dear Siesta's user:
I want to get the I-V curve. But I do not know how to decide the range of
the parameter of TS.TBT.Emax and TS.TBT.Emin by the value of TS.voltage.
For example, I think that, supposed the selected valtage 1.0 eV, the b
ias window is -0.5eV-0.5 eV. So the value of TS.TBT.Emin should be less than
-0.5 eV and the value of TS.TBT.Emax should be larger than 0.5 eV. Is it right?
Please tell me how to decide the range of the parameter of TS.TBT.Emax and
TS.TBT.Emin based on the TS.voltage?
For the second question, I do not know why, for the given voltage (such as
1.0 eV), the value of current is changed for the different energy window
defined by TS.TBT.Emin and TS.TBT.Emax.? I think that we will obtain the
special value of current for the given voltage as long as the bias window
between the energy window defined by TS.TBT.Emin and TS.TBT.Emax .
For my system, the parameters are followed:
TS.Voltage 1.0 eV
TS.TBT.Emin -0.5 eV
TS.TBT.Emax 0.5eV
I get the value of current is 4.17777609E-16
another thing:
T S.Voltage 1.0 eV
TS.TBT.Emin -1.0 eV
TS.TBT.Emax 01.0 eV
I get the value of current is 4.216753E-16
Thank you very much in advance!
Sincerely,
Mengqiu
