<div dir="ltr"><div><div><div><div>Dear Experts and Developers,<br><br></div>I have done band structure calculations for a lead based compound before and after inclusion of spin-obit interactions using PBE, PBEsol and TB-mBJ functional. I observed 0.5 eV reduction in the band gap value with PBE and PBEsol functionals. Whereas, TB-mBJ band gap shows 1 eV decrement. How can I understand this effect in terms of the spin-orbit interactions?. and why the spin orbit band gap is reduced by 1 eV for TB-mBJ while PBE and PBEsol functionals show 0.5 eV decrement? can someone help in understanding this in a detailed way!!!.<br><br></div>Thanking you in advance.<br><br></div>Regards<br></div>E.
