Dear all<br><br>I want the calculate the properties of <font style="font-size: 14px;">potassium titanate</font>. 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 <span class="grigio"></span><a href="http://www.quantum-espresso.org/pseudo/1.3/UPF/K.pz-sp-van.UPF" class="aranciolink">K.pz-sp-van.UPF</a> 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+?<br>
<br>thank you for reading <br><br>any hints will be deeply appreciated<br><br>vega<br><br clear="all"><br>-- <br>==================================================================================<br>Vega Lew ( weijia liu)<br>
