Dear Pausali, It seems that you are study the layer structured TMD crystal, not the monolayer. How about changing cell_dofree from '2Dxy' to 'all' or 'ibrave'? Cheers, Yun Dr Yun Wang | Senior Lecturer PhD Deputy Head of Discipline, Chemical Science Centre for Catalysis and Clean Energy

Dear Edmund, The (1x1x1) k-point mesh is not good enough to get the reliable data for your system. You may also need to consider the van der Waals correction due to the existence of the large atoms. Best regards, Yun Dr Yun Wang | Senior Lecturer PhD Centre for Clean Environment

Dear Reza, It seems that you chose the different energy ranges. In the first one, the energy is from 5 to 20 eV. And in the second one, the energy is from 0.5 to 2.0 eV. Best, Yun Dr Yun Wang | Senior Lecturer PhD Centre for Clean Environment and Energy | School of Environment & Sci
