<div dir="auto">Hi,<br />
I want to check the electronic structure of a few materials and think that DFT+U+V would be a good choice for doing so. I watched the QE summer school videos uploaded by Materials Cloud to see how to do this in QE. In particular, I am interested in sp2 hybridized 2D materials and thought that I should use something like what Prof. Matteo Cococcioni presents for sp3 hybridized silicon (<a href="https://youtu.be/64JKOF5lh2U?list=PL19kfLn4sO_-ox_Oylwi4IEb5qUp0dXfJ&t=2919" target="_blank">https://youtu.be/64JKOF5lh2U?list=PL19kfLn4sO_-ox_Oylwi4IEb5qUp0dXfJ&t=2919</a>). The problem is that hp.x does not work with the background s-orbitals. How do I determine what the U and V values should be without using hp.x? <br />
<br />
Thank you.</div>
