ANGEL - A Nonequilibrium Green's Function Solver for LEDs
Downloads | 06 Feb 2010 | Contributor(s):: sebastian steiger
Introducing ANGEL, a Nonequilibrium Green’s Function code aimed at describing LEDs.ANGEL uses a description close to the classic NEMO-1D paper (Lake et al., JAP 81, 7845 (1997)) to model quantum transport in a light-emitting diode (LED).ANGEL is the first 1D-heterostructure NEGF to include the...

Application of the Keldysh Formalism to Quantum Device Modeling and Analysis
Papers | 14 Jan 2008 | Contributor(s):: Roger Lake
The effect of inelastic scattering on quantum electron transport through layered semi-conductor structures is studied numerically using the approach based on the non-equilibrium Green's function formalism of Keldysh, Kadanoff, and Baym. The Markov assumption is not made, and the energy coordinate...

Atomistic Green’s Functions: The Beauty of Self-energies
Online Presentations | 16 Sep 2020 | Contributor(s):: Tillmann Christoph Kubis
This presentation gives an introduction to NEGF. It will be explained how self-energies cause NEGF to fundamentally differ from most other quantum methods. Atomistic examples of phonon and impurity scattering self-energies agree quantitatively with experiments.

Atomistic Modeling of Nano Devices: From Qubits to Transistors
Online Presentations | 12 Apr 2016 | Contributor(s):: Rajib Rahman
In this talk, I will describe such a framework that can capture complex interactions ranging from exchange and spin-orbit-valley coupling in spin qubits to non-equilibrium charge transport in tunneling transistors. I will show how atomistic full configuration interaction calculations of exchange...

Bandgap Manipulation of Armchair Graphene nanoribbon
Papers | 01 Sep 2020 | Contributor(s):: Lance Fernandes
Bandgap Manipulation is very important for various applications. Optical Devices need smaller Bandgap where as Diode's need larger Bandgap. Armchair graphene Nanoribbon (AGNR) has a special property where if the numbers of atoms are multiple of three or multiple of three plus one, they are...

Bandstructure in Nanoelectronics
Online Presentations | 01 Nov 2005 | Contributor(s):: Gerhard Klimeck
This presentation will highlight, for nanoelectronic device examples, how the effective mass approximation breaks down and why the quantum mechanical nature of the atomically resolved material needs to be included in the device modeling. Atomistic bandstructure effects in resonant tunneling...
