Dear PWSCF users,
       I know this question might be too general but I just want to give a
try.
       In PWSCF, there are two options for external field. One is 'tefield'
to simulate a sawlike potential, the other is 'lelfield' to simulate a
homogeneous electric field. Could you tell the difference between these two
options? Or can you link me to some useful references about how to use these
two types of external field?
       Thank you very much.
