  7. Metamaterials with low loss and gain

    Online Presentations | 28 Jan 2010 | Contributor(s): Mikhail A. Noginov

    Optical loss caused by absorption in metal and a need for active control are among the major challenges of plasmonic metamaterials. Both can be addressed by utilizing optical gain. Recent efforts aimed at the reduction of loss and the stimulated emission in nanoplasmonic systems with gain will be...

  11. 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.

  12. 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...

  13. Nanoelectronic Modeling Lecture 18: Introduction to RTDs - Quantum Charge Self-Consistency (Hartree)

    Online Presentations | 27 Jan 2010 | Contributor(s): Gerhard Klimeck

    In this semi-classical charge and potential model the quantum mechanical simulation is performed once and the quantum mechanical charge is in general not identical to the semi-classical charge.

  14. 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.

  15. Nanoelectronic Modeling Lecture 16: Introduction to RTDs - Realistic Doping Profiles

    Online Presentations | 27 Jan 2010 | Contributor(s): Gerhard Klimeck

    Realistic RTDs need extremely high doping to provide enough carriers for high current densities. However, Impurity scattering can destroy the RTD performance. The dopants are therefore typically spaced 20-100nm away from the central double barrier structure.

  16. Nanoelectronic Modeling Lecture 14: Open 1D Systems - Formation of Bandstructure

    Online Presentations | 27 Jan 2010 | Contributor(s): Gerhard Klimeck, Dragica Vasileska

    The infinite periodic structure Kroenig Penney model is often used to introduce students to the concept of bandstructure formation. It is analytically solvable for linear potentials and shows critical elements of bandstructure formation such as core bands and different effective masses in...

  17. Nanoelectronic Modeling Lecture 12: Open 1D Systems - Transmission through Double Barrier Structures - Resonant Tunneling

    Online Presentations | 27 Jan 2010 | Contributor(s): Gerhard Klimeck, Dragica Vasileska

    This presentation shows that double barrier structures can show unity transmission for energies BELOW the barrier height, resulting in resonant tunneling. The resonance can be associated with a quasi bound state, and the bound state can be related to a simple particle in a box calculation.
