Each number of carriers specified in the array is added to the value of {{TAG|NELECT}} and the chemical potential computed for the list of temperatures specified by {{TAG|ELPH_SELFEN_TEMPS}}.
From each carrier density specified in the array, a positive (electron doping) or negative (hole doping) number of electrons is added to the value of {{TAG|NELECT}} and the chemical potential computed for the list of temperatures specified by {{TAG|ELPH_SELFEN_TEMPS}}.
A positive number adds electrons (electron doping), while a negative one removes (hole doping).


Instead of specifying the number of carriers, it is possible to specify an additional carrier density in units of <math>{m^{-3}}</math> by using the {{TAG|ELPH_SELFEN_CARRIER_DEN}} tag. Alternatively, one can specify the chemical potential and determine the carrier concentration using {{TAG|ELPH_SELFEN_MU}}.

Description: list of additional carrier densities in units of at which to compute the electron-phonon self-energy and transport coefficients.


From each carrier density specified in the array, a positive (electron doping) or negative (hole doping) number of electrons is added to the value of NELECT and the chemical potential computed for the list of temperatures specified by ELPH_SELFEN_TEMPS.

Instead of specifying a carrier density, it is possible to explicitly specify the additional number of electrons to be added by using the ELPH_SELFEN_CARRIER_PER_CELL tag. Alternatively, one can specify the chemical potential and determine the carrier concentration using ELPH_SELFEN_MU.

The information related to the chemical potential calculation can be found under the Chemical potential calculation section in the OUTCAR.
