I am working on tight binding formulation of CNTs. The transmission function T(E), which is the trace of the product of the lead self energies and the retarded and advanced green's function.
This value is a complex entity. T(E) needs to be calculated at different energy levels and then integrated to find the current flowing. My question is: How does one integrate the complex T(E) over the real axis of energy. Do I take just the real part and integrate or integrate both real and complex part separately and then take the modulus? Please help
