[Pw_forum] very large value 'U' obtained for 'GaAs' by linear response method

[Bramha Pandey]

First of all thank you very much Dear Prof.Stefano.
I have change the input as ZB 'GaAs' structure and calculate the 'U' value
for both 'Ga' and 'As' which is given bellow.
But i wondered to see the 'U' value of 'Ga' 1010.79 which is quite large so
how can i figure out this is  correct or wrong?
No of Atom        U_Ga                       U_As
