[Wannier] Cu2ZnSnSe and Cu2ZnSnS (Boltzwann Calculations)

[Alex Gal Aziz]

I am investigating Cu2ZnSnSe4 and Cu2ZnSnS4.


I have been using VASP compiled with Wannier functions to generate the initial projections and then generate the MLWF using the Disentanglement procedure. I have checked the band structures and they look correct with the appropriate band gaps (~1.5 for Cu2ZnSnS4 and 0.9 Cu2ZnSnSe4).


When I check the Seebeck using BoltzWann I seem to get similar results in both cases. I am trying to figure out if this seems plausible due to the difference in band gaps.


Any suggestions would be welcomed


Thanks
