Nanoelectronic Modeling Lecture 22: NEMO1D  Motivation, History and Key Insights
07 Feb 2010   Contributor(s):: Gerhard Klimeck
The primary objective of the NEMO1D tool was the quantitative modeling of high performance Resonant Tunneling Diodes (RTDs). The software tool was intended for Engineers (concepts, fast turnaround, interactive) and Scientists (detailed device anaysis). Therefore various degrees of...

Nanoelectronic Modeling Lecture 21: Recursive Green Function Algorithm
07 Feb 2010   Contributor(s):: Gerhard Klimeck
The Recursive Green Function (RGF) algorithms is the primary workhorse for the numerical solution of NEGF equations in quasi1D systems. It is particularly efficient in cases where the device is partitioned into reservoirs which may be characterized by a nonHermitian Hamiltonian and a central...

ANGEL  A Nonequilibrium Green's Function Solver for LEDs
07 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 NEMO1D paper (Lake et al., JAP 81, 7845 (1997)) to model quantum transport in a lightemitting diode (LED).ANGEL is the first 1Dheterostructure NEGF to include the...

Nanoelectronic Modeling Lecture 20: NEGF in a Quasi1D Formulation
27 Jan 2010   Contributor(s):: Gerhard Klimeck, Samarth Agarwal, Zhengping Jiang
This lecture will introduce a spatial discretization scheme of the Schrödinger equation which represents a 1D heterostructure like a resonant tunneling diode with spatially varying band edges and effective masses.

Nanoelectronic Modeling Lecture 19: Introduction to RTDs  Asymmetric Structures
27 Jan 2010   Contributor(s):: Gerhard Klimeck
This lecture explores this effect in more detail by targeting an RTD that has a deliberate asymmetric structure. The collector barrier is chosen thicker than the emitter barrier. With this setup we expect that the tunneling rate into the RTD from the emitter is faster than the tunneling rate...

Nanoelectronic Modeling Lecture 17: Introduction to RTDs  Relaxation Scattering in the Emitter
27 Jan 2010   Contributor(s):: Gerhard Klimeck
Realistic RTDs will have nonlinear electrostatic potential in their emitter. Typically a triangular well is formed in the emitter due to the applied bias and the emitter thus contains discrete quasi bound states.

Nanoelectronic Modeling: From Quantum Mechanics and Atoms to Realistic Devices
25 Jan 2010   Contributor(s):: Gerhard Klimeck
The goal of this series of lectures is to explain the critical concepts in the understanding of the stateoftheart modeling of nanoelectronic devices such as resonant tunneling diodes, quantum wells, quantum dots, nanowires, and ultrascaled transistors. Three fundamental concepts critical to...
