It is worth noting that the performance of van der Waals (vdW) functionals in the presence of SOC is comparatively less effective, except for the SCAN+rVV10 vdW-DF. This observation suggests that the SCAN+rVV10 vdW-DF functional is better suited for capturing the interlayer interactions and accurately describing the electronic structure of TMDC systems in the presence of SOC. By considering the SOC effects and incorporating the appropriate vdW functionals, this study provides a comprehensive understanding of the structural and electronic properties of TMDC materials. These insights contribute to the exploration and utilization of TMDCs in various fields, such as spintronics, catalysis, and quantum computing. previous studies . In this study, we conducted a comparison of the Fermi surfaces between the NSOC and SOC cases. Notably, we observed that the Fermi surfaces were almost identical in both cases, irrespective of the presence of SOC. As the Fermi surfaces for the majority of systems were shown in the NSOC cases, we decided not to display them for the SOC cases.
