   Teaching Materials | 04 Feb 2010 | Contributor(s):: Mehdi Salmani Jelodar, Supriyo Datta (editor)

   Lecture notes for the Fall 2009 teaching of ECE 495: Fundamentals of Nanoelectronics.

2. Nanoelectronic Modeling Lecture 20: NEGF in a Quasi-1D Formulation

   Online Presentations | 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.

3. Nanoelectronic Modeling Lecture 19: Introduction to RTDs - Asymmetric Structures

   Online Presentations | 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 set-up we expect that the tunneling rate into the RTD from the emitter is faster than the tunneling rate...

4. Nanoelectronic Modeling Lecture 17: Introduction to RTDs - Relaxation Scattering in the Emitter

   Online Presentations | 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.
