Dear Laurence Marks Sir,
a) Sir it is an insulator experimentally....conductivity 10^(-7) S/cm
But as you have told I can not find any gap from the "dirty DOS" as
given below.
band 154 -0.0035740378 0.0033882757 0.100000D+01
band 155 0.0044596281 0.0079912962 0.100000D+01
Then why it is not showing any gap?....we still believe that structural
model is ok!
b) convergence criteria are 0.0001 for both energy and charge
final value of :DIS is 0.0070262
Charge convergence is achieved up to 0.0438054
Energy convergence is achieved up to 0.000296635
c) No I am not doing a minimization...rather a normal SCF
Sir, the XRD is same as it is obtained experimentally. It has exactly the
same number of peaks at same relative intensity at the same 2theta value.
But from "dirty DOS" it is clear that the material is not showing any gap
while we are trying to force it by applying GGA+U. May be this is the reason
for not having the convergence yet!.....now we have to find out the reason
for this.
Any suggestion in this regard will be very helpful for us.
with best regards,
