[Wien] A question about unit of electric field in in0

[zhao]

Dear Prof. P. Blaha,

In your paper, PRB-63-165205(2001), you say that external potential
100mRy corresponds to 700 kV/mm. When I tried to get this unit
transformation, I was confused by something. The following is my
problem. 
--------------------------------------------------
c=8*sqrt(3)*a0
a0=5.65 Angs
Efield= 0.1Ry/c=0.1*13.6V/(8*sqrt(3)*a0)= 173 kV/mm
--------------------------------------------------

I cannot get 700 kV/mm. Can you tell me what's wrong with myself?
Thank you very much.



Best wishes,

Sincerely,
Yong-Hong Zhao
