EPW Forum

Hi dear experts and users:

Currently i inspect the electron-plasmon in semi-conductors i have two questions:

1 how can i adjust the doping carrier concentration in intrinsic materials ?

2 What can i do with EPW code in the plasmon investigation ? can it calculate the loss function and the plasmon energy ?



Best regards

Hello,

No, EPW doesn't calculate the loss function and plasmon energy; for those you should use e.g. Yambo.
EPW implements the approach of https://journals.aps.org/prb/abstract/1 ... .94.115208 for calculating the el-plasmon self-energy in a degenerate semiconductor. The carrier concentration is given by 'nel' in the input.

Best wishes,
Carla
