Dear wien2k users<br />
I want to use scan exchange correlation for optimization of binary semiconductors(GaP).But the lattice constant varies with Rkmax at third decimal place even on increasing rkmax up to 11 and increasing ifft enhancement factor up to 4 in case.in0.although the E-V graph is smooth. Please suggest some solution to converge the lattice constant with rkmax.<br />
the results obtained are<br />
RK <br />
8.0 5.4663<br />
8.5 5.4651<br />
9.5 5.4642<br />
10.0 5.4633<br />
<br />
Thanks<br />
