Select tutorials in nanotechnology, a part of the
2010 NCN@Purdue Summer School: Electronics from the Bottom Up.
Qualitative treatment of the simulated design (GaN based RTD)has to be done in order to explore more properties of RTD under experimentation. This results in building a novel device which has the...
Nanoelectronic Modeling Lecture 23: NEMO1D - Importance of New Boundary Conditions
09 Mar 2010 | Online Presentations | 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...
Nanoelectronic Modeling Lecture 24: NEMO1D - Incoherent Scattering
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...
