Hi, dear friends
Here I met one small problem, from the .AVTRANS file, I can get the
relationship of Transmission coefficient(T) and Total Energy(E). Now,
just like the attached figure, how can I get the relationship between
Transmission Coefficient(T) and Fermi Energy(Ef) ?
Hi Jason,
from Siesta manual, which I humbly suggest to read carefully:
"The energy scale in tbtrans is shifted so that the Fermi level of the
system, if no voltage were
applied, is zero. When computing the transmission function of a zero
bias calculation, the
transmission at the Fermi level is then given by T(E=0). When there is a
finite bias, the Fermi
energy of the left electrode is placed at V/2, and that of the right
electrode at -V/2"
