[QE-users] Regarding Vacuum level

[mohaddeseh abbasnejad]

Dear users,

Hello,

I have faced with a problem which though it is simple, I can not do it.
Actually, I want to plot data of density of states with reference to vacuum
level (E_vac).
As it is well understood, the produced data are with reference to average
electrostatic potential (E_aep).
However, I have calculated the vacuum level (E_vac) using work function
calculations.
I was wondering if that is correct to obtain the data with reference to
vacuum level by shifting the data by E_vac value. I mean that the desired
value will be obtained by subtracting the E_vac from E_aep, setting the
vacuum level as zero energy level. Is it true?
Any comment will be appreciated.
Thanks in advance.

Regards,
Mohaddeseh

Is it correct to just shift data
