[Pw_forum] questions about the peseudopotential for potassium titanate

[vega lew]

Dear all

I want the calculate the properties of potassium titanate. And I want to use
the pw91 functionals for the whole caculation. But I find the
peseudopotential for K is something different with the Ti and O. From the
name of pp, we could see functionals for K is different from Ti and O. Do
you think I could use
K.pz-sp-van.UPF<http://www.quantum-espresso.org/pseudo/1.3/UPF/K.pz-sp-van.UPF>with
the O.pw91-van_ak.UPF and Ti.pw91-sp-van_ak.UPF to describe the
potassium titanate. Actually I want to use pw91 functionals for the
calculation. How could I deal with the K+?

thank you for reading

any hints will be deeply appreciated
