<div dir="ltr"><div><div><div><div><div><div>Dear all,<br><br></div>I would like to do
calculations with DFT+U of ZnSe material using Quantum esspresso. As
per I know there is different U for each distinct type of hubbard
atom.And typical value of U is rarely larger than 7-8 eV and in most
case it lies between 0<U<5. but how do we know that which value of
U satisfied for Zn atom .Is there we do any type of convergence to
calculate U parameter.<br></div>And in case we include U parameter for
Se the error has ocurred ' pseduopotential is not inserted yet'. So is
it sufficient to not include U parameter for Se to do DFT+U calculations
for ZnSe.<br><br></div>Regards<br></div>swati khatta<br></div>panjab University <br></div>chandigarh</div>
