ELPH_SELFEN_TEMPS_RANGE = [real array] 

Description: The range of temperatures (in K) at which to compute the phonon-mediated electron self-energy and transport coefficients.

Mind: Available as of VASP 6.5.0

This list of temperatures is used to determine the chemical potential, the occupation factors entering the electron self-energy due to electron-phonon coupling as well as the transport coefficients in the context of a transport calculation.

A range of temperatures can be defined using ELPH_SELFEN_TEMPS_RANGE = l u n, where:

  • l is the lower limit of the temperature range.
  • u is the upper limit of the temperature range.
  • n is the number of steps between the two limits.

For example, ELPH_SELFEN_TEMPS_RANGE = 0 700 41 would create a list of 41 points from 0 K to 700 K. This is printed in the OUTCAR file:

elph_selfen_temps=
      0.000
     17.500
     35.000
  ...
    665.000
    682.500
    700.000

At each temperature an electron-phonon calculation is performed, rather than defining it manually using ELPH_SELFEN_TEMPS.
