1. Nanotechnology 501 Lecture Series

   5.0 out of 5 stars 

   22 Feb 2005 | Series | Contributor(s): Gerhard Klimeck (editor), Mark Lundstrom (editor), Joseph M. Cychosz (editor)

   Welcome to Nanotechnology 501, a series of lectures designed to provide an introduction to nanotechnology. This series is similar to our popular lecture series Nanotechnology 101, but it is directed at the graduate students and professionals.

2. Quantum Mechanics for Engineers: Podcasts

   0.0 out of 5 stars 

   07 Jul 2008 | Series | Contributor(s): Dragica Vasileska, Gerhard Klimeck, David K. Ferry

   This course will introduce the students to the basic concepts and postulates of quantum mechanics. Examples will include simple systems such as particle in an infinite and finite well, 1D and 2D harmonic oscillator and tunneling. Numerous approximation techniques, such as WKB method, time-dependent and time-independent perturbation theory, variational methods and numerical solution methods of the 1D Schrödinger equation, will be presented. The importance of quantum-mechanics in todays life ...

3. Quantum Mechanics: Stationary Perturbation Theory

   0.0 out of 5 stars 

   10 Jul 2008 | Series | Contributor(s): Dragica Vasileska, Gerhard Klimeck

   Stationary perturbation theory is concerned with finding the changes in the discrete energy levels and the changes in the corresponding energy eigenfunctions of a system, when the Hamiltonian of a system is changed by a small amount. In this section we provide reading material regarding stationary perturbation theory, slides and homework assignments. Reading Material: Stationary Perturbation Theory Reading Material: Stationary Perturbation Theory Examples and Stark Effect Slides: ...

4. Solar Cells Operation and Modeling

   19 Jul 2010 | Teaching Materials | Contributor(s): Dragica Vasileska, Gerhard Klimeck

   This set of slides decribes the basic principles of operation of various generations on solar cells with emphasis to single crystalline solar cells. Next, semiconductor equations that describe the operation of a solar cell under simplified conditions is given. Finally, modeling of single junction solar cells is described. Modeling of solar cells with Silvaco simulation software is also outlined. NSF

5. Quantum Mechanics: WKB Approximation

   0.0 out of 5 stars 

   09 Jul 2008 | Series | Contributor(s): Dragica Vasileska, Gerhard Klimeck

   In physics, the WKB (Wentzel–Kramers–Brillouin) approximation, also known as WKBJ (Wentzel–Kramers–Brillouin–Jeffreys) approximation, is the most familiar example of a semiclassical calculation in quantum mechanics in which the wavefunction is recast as an exponential function, semiclassically expanded, and then either the amplitude or the phase is taken to be slowly changing. This method is named after physicists Wentzel, Kramers, and Brillouin, who all developed it in 1926. In ...

1. The NEGF Approach to Nano-Device Simulation

   site

   The non-equilibrium Greens function (NEGF) formalism provides a powerful conceptual and computational framework for treating quantum transport in nanodevices. It goes beyond the Landauer approach for ballistic, non-interacting electronics to include inelastic scattering and strong...

2. ABACUS—Introduction to Semiconductor Devices

   site

   When we hear the term semiconductor device, we may think first of the transistors in PCs or video game consoles, but transistors are the basic component in all of the electronic devices we use in our daily lives. Electronic systems are built from such components as transistors, capacitors,...

3. NCN Nanoelectronics

   site

   Microelectronics was one of the great technologies of the 20th century. Progress in technology has now taken microelectronics to the nanoscale, but nanoelectronics is not yet an engineering discipline. The NCN has a vision to re-invent electronics from the “bottom-up,” by which we...
