Dear sir, Kindly help me to understand some of the parameters of the Bolztrap input file <case.intrans> in the user guide.
In the 2nd line from the bottom in <case.intrans>, i have seen a parameter which is described in a short sentence as "number of fixed doping". Is this means, we are choosing the number of doping concentrations where the properties could be evolved...? I think, with a predefined doping numbers, we should also give the corresponding values of concentrations in the below (ie. 1st line from the bottom). The default values defined in the Botlztrap user guide are ---------------------------------------------------------------------- 2 : number of fixed dopings 1E20 -1E20 : fixed doping levels in cm^-3 --------------------------------------------------------------------------- By the combinations of these two parameters, one can able to keep the chemical potential at a fixed places (given by these concentration values) in DOS spectrum and obtain the transport properties for corresponding doping levels. is n't it ..? what is the meaning of negative sign in front of concentration values (1st line from the bottom)..? Is it represents the concentration for electrons..? (means, holes will get +ve sign). It is a great help for me, if you explains these parameters in terms of their physical significance. thanking you and looking forward to answers. regards, Ch. Venkatesh, C/o. Prof. V.
