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}}.
For example, {{TAGO|ELPH_SELFEN_CARRIER_PER_CELL|0.001 0.01 0.1}} means that the number of electrons per cell {{TAGO|NELECT|18}} will be increased by the specified values which will produce the following table in the <tt>Chemical potential calculation</tt> section in the {{FILE|OUTCAR}} file

ELPH_SELFEN_CARRIER_PER_CELL = [real array]
Default: ELPH_SELFEN_CARRIER_PER_CELL = 0.0 

Description: List of additional number of carriers for which to compute the electron-phonon self-energy and transport coefficients.


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

For example, ELPH_SELFEN_CARRIER_PER_CELL = 0.001 0.01 0.1 means that the number of electrons per cell NELECT = 18 will be increased by the specified values which will produce the following table in the Chemical potential calculation section in the OUTCAR file

The number of elements in ELPH_SELFEN_CARRIER_PER_CELL will determine the number of columns in the tables above, while ELPH_SELFEN_TEMPS the number of rows.

Instead of specifying the number of carriers, it is possible to specify an additional carrier density in units of via the ELPH_SELFEN_CARRIER_DEN tag. Alternatively, one can specify the chemical potential and determine the carrier concentration using ELPH_SELFEN_MU.
