Title: Question:Relationship between DOS and transmission spectrum
Post by: gny1988 on May 12, 2010, 10:19

the version of our atk is 2.0. And I want to know if the current is the integral of transmission coefficient or the integral of product of transmission coefficient and density of states. Or when calculate transmission coefficient, atk 2.0 has already considered the density of states.

Yes, it is already taken into account in the transmission. The transmission is however weighted with the Fermi distribution of the leads when integrating it for the current. You can find all these details in the methodology papers (http://quantumwise.com/publications/scientific-publications).
