[Pw_forum] unit of electrostatic potential

[ahmet atay]

Dear QE Users,
I try to calculate  average electrostatic potential of GaN/AlN
superlattices (001).
I have performed  pw.x, pp.x (plot_num=1)  and average.x, respectively.
Lastly, I have curved  V_average(?) - Z(Angstrom) graph. So far everything
is okay. But I couldn t be sure that unit of V_average is Ryd. or eV.

I think V_average axis is Rydberg . am I Right ?
