Transmission spectrum of InSe

[gozde]

Hi all,

I am a new user of ATK. I have made a tutorial of calculating the transmission spectrum of graphene and MoS2. Now I try to calculate transmission spectrum of 2D perfect sheet of InSe, however I can not use ATK-SE. It is written that " Internally invalid: The basis set is incompatible with the configuration." My question is, what calculator can be used for obtaining transmission spectrum of InSe or GaSe?

Only DFT. I am not aware of any semi-empirical parameter sets for those materials.

Thank you for your answer. Where can I see for which materials SE parameter sets are defined?

Thanks for the link. Also, the Slater-Koster parameter group and set are invisible even though it is written "ATK contains a Slater-Koster model (DFTB) for Mo-S already, contained in the (admittedly experimental) CP2K set" in the transmission tutorial. Is this parameter set removed or is there something wrong with my application?

Sorry for the confusion, see https://forum.quantumatk.com/index.php?topic=6195.0

Thank you very much, i will do the calculation with DFT-LCAO approach.
