The non-equilibrium Greens function (NEGF) formalism provides a powerful conceptual and computational framework for treating quantum transport in nanodevices. It goes beyond the Landauer approach for ballistic, non-interacting electronics to include inelastic scattering and strong correlation effects at an atomistic level.
Check out Supriyo Datta's NEGF page for more information, or browse through the various resources listed below.

I have been studying the nanoelectronics lectures by Dr. Supriyo Datta & also followed his NanohubU course Fandamentals of Nanoelectronics II. So far it's the knowledge I have about nanoelectronics & …
How to consider electron-photon interaction w/o using self-energy?
Hi, In negf, interactions are considered as self-energies. For electron-photon interaction, a perturbation Hamiltonian is derived and then self-energy is found using coupled-field theory. Now, my …
Sign of imaginary part of self-energy for hole Hamiltonian
Prof Datta in his QTAT Exercise Ch8, discusses that the imaginary part of the contact self-energy should be negative while the real part will tend towards zero for large energies in both directions. …

NEGF Formulism Question
Hi, I'm not too familiar with the NEGF formalism. But had a very basic question. I've read that NEGF can be viewed as a "Quantum Boltzmann Equation". When taking moments of the classical …
In the time-dependent NEGF equation, given a sigma_in(t,t') due to the dot, I am getting an I-V equation that is making it difficult for me to group terms. For instance, looking at the analogue of …
What I want to do is building an aluminum quantum dot coupled to aluminum leads to observe Coulomb Blockade. To form the tunnel barriers we oxidize the Al in a plasma without any detailed knowledge …
