[Wien] Chemical Potential Boltztrap

[elsasab at alumni.uv.es]

Dear Wien2k useres,

I just started to use the Boltztrap program. I have read a lot of papers using this program but I still have some questions related with the input and output files.

Firstly: In most of the published articles they represent the seebeck coefficient as a function of the chemical potential. Usually in the x-axis they have zero value for the chemical potential; for example the case of Bi2Te3 in the main article. How do they get the zero value even though in the Bi2Te3.trace file there no zero value for the chemical potential. Do we need to substract a certain value from the column of the chemical potential?

Secondly: in the case.intrance file there are two parameters that I can't understand the difference between them: ecut and efcut. As I understand that the chemical potential and the fermi level are synonym and they are equal to the fermi energy at 0 kelvin. So I think this parameters (ecut and efcut) should be synonym too. Also in the case.intrance file at the we should insert the value of the fermi level. How can we get this value? Do we have to put the value of the Fermi energy that we have in case.scf file?

Best regards
