Ah! Thank you. Ok, the form will be something like this (for a uniform
electrical field of +0.5 eV/angs along the Z direction), but I'm still
not sure how to interpret the FUNCTION keyword and if I'm getting this
right. Any ideas?

   &EXTERNAL_POTENTIAL
      FUNCTION (A/B)*Z
      PARAMETERS A B
      VALUES [eV] 5.0  [angstrom] 10.0
    &END
