ELPH_SELFEN_CARRIER_DEN = [real array]
Default: ELPH_SELFEN_CARRIER_DEN = 0.0

Description: list of additional carrier densities in units of $m^{-3}$ 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.
