09 Mar 2010   Contributor(s):: Gerhard Klimeck
One of the key insights gained during the NEMO1D project was the development of new boundary conditions that enabled the modeling of realistically extended Resonant Tunneling Diodes (RTDs). The new boundary conditions are based on the partitioning of the device into emitter and collector...

Nanoelectronic Modeling Lecture 24: NEMO1D  Incoherent Scattering
09 Mar 2010   Contributor(s):: Gerhard Klimeck
Incoherent processes due to phonons, interface roughness and disorder had been suspected to be the primary source of the valley current of resonant tunneling diodes (RTDs) at the beginning of the NEMO1D project in 1994. The modeling tool NEMO was created at Texas Instruments to fundamentally...

Nanoelectronic Modeling Lecture 26: NEMO1D 
09 Mar 2010   Contributor(s):: Gerhard Klimeck
NEMO1D demonstrated the first industrial strength implementation of NEGF into a simulator that quantitatively simulated resonant tunneling diodes. The development of efficient algorithms that simulate scattering from polar optical phonons, acoustic phonons, alloy disorder, and interface roughness...

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...

Derivation of the phononlimited mobility is reviewed for electrons in bulk (3D) orquantum confined (2D and 1D) semiconductor structures. Analytical estimates are madethat show the mobility in quantum confined structures is, in general, lower or no higherthan in nonconfined ones.
