Hello everyone,<div><br /></div><div>I am trying to compare with HSE06 functional using VASP and CP2K. I found out that the band gap calculated using VASP is about 3.7 eV for UiO-66 which is very close to the experimental value 3.6-3.7 eV. </div><div><br /></div><div>However, when I use CP2K, the band gap is 4.07 eV, which is almost the same with the data reported by the following paper. (Understanding Intrinsic Light Absorption Properties of UiO-66 Frameworks: A Combined Theoretical and Experimental Study, <span style="box-sizing: border-box; outline: none; color: rgb(0, 0, 0); font-family: Roboto, arial, sans-serif; font-size: 12px;"><i style="box-sizing: border-box; outline: none; padding-right: 0.3125rem;">Inorg.

Or any room to improve the accuracy.
