Hello Everyone! There is given a parameter Excitation energy when we calculate scattering matrix or LDOS. Can anyone please give more details about this parameter.All I can understand is that it is the energy with which electron travel in scattering region. when we calculate LDOS we get the probability with which electron of that excitation energy can move in crystal.
What is confusing that I have already applied voltage across the device. How still conductance changes when I change the value of Excitation energy. Is it calculating conductance for that energy level only or what? Information about how this value get processed would be helpful.
