When electrons used to interact with source with Channel ,where we have kept our GNR,and both sides we have kept graphene electrodes,we can calculate Transmission function by simply the Fermi Function difference ,multiplied by q/hbar, then why do we need Caroli NEGF implementation of the Landauer-Bttiker Formula to determine Transmission function.
Dear Kislyakov,it means when we are giving more bias to our system it is the other name of Non equilibrium Green's function,when we are calculating Transmission amplitude.
regards
There are many ways to Landauer-Buttiker Formula, Surender. NEGF is one of them.
Ok Kislyakov,thanks but my self energies and broadening functions are coming in complex forms,does it make any sense physically or not ,i am confused i case of my graphnene nano ribbons systems
