Dear Raha,

I have encountered this issue before. I think your only problem is the ordering of the atoms of your contacts.
Please, have a look at section 2.1.1.2 of this guide<http://www.dftb-plus.info/fileadmin/DFTB-Plus/public/recipes-negf/html/transport/specifying_geometry.html>

Cheers,
Alessandro

Hello!

I am trying to find transmission of a single molecule sandwiched between two CNT electrodes. My calculations got converged but the final transmission order is very low, almost zero.
Here are attached the input and ouput files. Any help will be really appreciated.

Best regards,
Raha
