transport calculation

Asked by maluneelambari on 2018-10-01

Hi,
1) While doing transport through a system do we need to isolate in any direction? Is it okey if it is continuous in all direction?
2)What all things we need to care when we use transiesta to calculate transport through a metal/ 2 dimensional semiconductor/metal system?

Thank you

1) It is ok to have periodicity. TranSiesta/TBtrans will automatically truncate the semi-infinite directions
2) Same thing as for *any* other material. The electrodes needs to be screened from the device region.

Thanks Nick Papior, that solved my question.
