Poisson Equation Solvers
08 Jun 2010  Teaching Materials  Contributor(s): Dragica Vasileska
There are two general schemes for solving linear systems:
Direct Elimination Methods, and
Iterative Methods.
All the direct methods are, in some sense, based on the standard Gauss Elimination technique, which systematically applies row operations to transform the original system of equations into a form that is easier to solve. This section overviews the LU Decomposition method which, although functionally equivalent to the Gauss Elimination method, does provide some additional …

Poisson Equation Solvers  General Considerations
08 Jun 2010  Teaching Materials  Contributor(s): Dragica Vasileska
We describe the need for numerical modeling, the finite difference method, the conversion from continuous set to set of matrix equations, types of solvers for solving sparse matrix equations of the form Ax=b that result, for example, from the finite difference discretization of the Poisson Equation.

Quantum Bound States Described
02 Jul 2011  Teaching Materials  Contributor(s): Dragica Vasileska
This write up describes basic concepts of closed systems and bound states calculations. Emphasis is placed on bound states calculation for infinite potential well, finite potential well, triangular well and numerical calculation of the bound states for wells with arbitrary shape (using the socalled shooting method).

Quantum Bound States Exercise
16 Jun 2010  Teaching Materials  Contributor(s): Gerhard Klimeck, Parijat Sengupta, Dragica Vasileska
Exercise Background
Quantummechanical systems (structures, devices) can be separated into open systems and closed systems. Open systems are characterized with propagating or current carrying states. Closed (or bound) systems are described with localized wavefunctions. One such system is a triangular potential well in MOS capacitors; another one is rectangular quantum well in heterostructure devices. In addition to this, every observable in Quantum Mechanics (like position, momentum, energy) …

Quantum Mechanics: Hydrogen Atom
09 Jul 2008  Teaching Materials  Contributor(s): Dragica Vasileska, Gerhard Klimeck
The solution of the Schrödinger equation (wave equations) for the hydrogen atom uses the fact that the Coulomb potential produced by the nucleus is isotropic (it is radially symmetric in space and only depends on the distance to the nucleus). Although the resulting energy eigenfunctions (the "orbitals") are not necessarily isotropic themselves, their dependence on the angular coordinates follows completely generally from this isotropy of the underlying potential: The eigenstates of the ...

Quantum Mechanics: The story of the electron spin
09 Jul 2008  Teaching Materials  Contributor(s): Dragica Vasileska, Gerhard Klimeck
One of the most remarkable discoveries associated with quantum physics is the fact that elementary particles can possess nonzero spin. Elementary particles are particles that cannot be divided into any smaller units, such as the photon, the electron, and the various quarks. Theoretical and experimental studies have shown that the spin possessed by these particles cannot be explained by postulating that they are made up of even smaller particles rotating about a common center of mass (see ...

Quantum Tunneling Exercise
16 Jun 2010  Teaching Materials  Contributor(s): Gerhard Klimeck, Parijat Sengupta, Dragica Vasileska
Exercise Background
Tunneling is fully quantummechanical effect that does not have classical analog. Tunneling has revolutionized surface science by its utilization in scanning tunneling microscopes. In some device applications tunneling is required for the operation of the device (Resonant tunneling diodes, EEPROMs â�� floating gate memories), but in some cases it leads to unwanted power dissipation, such as gate leakage in both MOS and Schottky transistors.
