Hi Transiesta developers and users,
I want to obtain the transmission matrix in Bloch states representation. In
this representation, transmission matrix is written in the form of T= t *
t^\dagger. Here t is a matrix with elements presenting transmission form one
Bloch state in left electrode to another Bloch state in right electrode. As I
know, in NEGF, the transmission matrix is in atomic orbital representation and
these atomic orbitals are those in the scattering region. I think there must be
a transformation from the atomic orbital representation to the Bloch state
representation. My question is, does anyone know how to do this transformation?
Any idea and any reference is welcome.
Thank you very much!
best wishes,Yun-Peng
