<div dir="ltr"><div>Dear sir,<br><br>Kindly
help me to understand some of the parameters of the Bolztrap input file <case.intrans> in the user guide. <br>
<br>
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<br>
means, we are choosing the number of doping concentrations where the<br>
properties could be evolved...? I think, with a predefined doping<br>
numbers, we should also give the corresponding values of<br>
concentrations in the below (ie. 1st line from the bottom). <br><br></div>The default values defined in the Botlztrap user guide are <br><br>----------------------------------------------------------------------<br>2 : number of fixed dopings<br>
1E20 -1E20 : fixed doping levels in cm^-3<br><div><div>---------------------------------------------------------------------------<br><br>By the
combinations of these two parameters, one can able to keep the<br>
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 ..?<br>
<br>
what is the meaning of negative sign in front of concentration<br>
values (1st line from the bottom)..? Is it represents the concentration for electrons..? (means, holes will get +ve sign).<br>
<br>
<br>
It is a great help for me, if you explains these parameters in terms<br>
of their physical significance.<br>
<br>
thanking you and looking forward to answers.<br>
