calculations in finite electric fields are typically used
to compute molecular response properties, such as dipole moments,
polarizabilities and higher-order non-linear optical (NLO) properties,
as well as their derivatives with respect to molecular geometry
etc...; especially for methods where analytical expressions are
not programmed. You may take a look at runtypes based on the use
of finite electric fields:

runtyp=raman
runtyp=ffield

You may also take a look at runtyp=tdhf for analytical computations
of frequency-dependent NLO for Hartree-Fock and DFT.

KInd regards,
Alex Granovsky

>Dear Pavel,
>I can just say that electron mobility is like the smoothness in the electron/hole motion... and as seen from the provided link, it is well connected to the conductivity....and drift velocity.. Also for smaller samples, i feel the small electric fields will have profound effects on conductivity... of course it will be quite different from macro one.
