Dear Malika,

the Fock exchange (also known as exact exchange) included in PBE0 is very computationally intensive, it is unlikely that you'll be able to run it on a laptop.

kind regards

Hello,
I noticed that bandgap of ZnO is underestimated when using GGA. It seems like PBE0 is the most accurate methode in my case to find a value close to the experimental one. Neverthless I don't know how to use it and how much time i'll need to run it in a laptop with 8 processors.
Can you please clarify my doubts?
