<p align="justify" style="margin-bottom:0in;line-height:100%"><font size="2">Hope You are doing well.<br></font></p>
<p align="justify" style="margin-bottom:0in;line-height:100%"><span style="font-size:small">A system which I’ve considered comprised </span>silicene<span style="font-size:small"> on Halogen passivated SI 111 surface. I want to extract Tight Binding (TB) Hamiltonian of only </span>silicene<span style="font-size:small"> layer from whole Hamiltonian of the system. I could do it by WANNIER90 in the absences of spin-orbit interaction (SOI) by sp3 hybridized orbitals on each Si atoms of </span>silicene<span style="font-size:small"> as projections. By turning the SOI on, however, I’ve increased energy cut-off from 40(Ry) to 60(Ry) and k-point sampling from 20 20 1 to 36 36 1, but I couldn’t get the correct interpolated band structure of only </span>silicene<span style="font-size:small"> layer and its TB Hamiltonian, accordingly. Also, I’ve used other projections (one Pz orbital in each Si atom from </span>silicene<span style="font-size:small"> and sp2 hybridized orbitals in middle of Si-Si bonds with its nearest neighbors). In this case spreading of Wannier functions were so large. Herewith I’ve attached my QE and WANNIER90 input files for Your consideration. Would you do a favor by giving me any guidance to fix this problem? It would be a great help and I’ll appreciate it.</span><br></p>
