Dear users <br>i am calculating the band structure of a system with LDA+U and i have used (SO) as well. when i run LDA+U with (SO) on, Valence band is touching the fermi level and VB maximum is nearly at zero and the total gap is nice. when i put SO off i get a gap between VB maximum and fermi level, but my band gap value is reduced to 1/2 of the original value.<br>
Please tell me what is the definition of fermi level in wien2k. <br><br>With Regards<br><br>Idris Hamid<br>
