Can we define unique effective masses in Si nanowires?
06 Jul 2008  Teaching Materials  Contributor(s): Dragica Vasileska, Gerhard Klimeck
This exercise teaches the users that for small nanostructures the concept of the effective mass becomes vague and in order to properly describe nanostructures one has to take into account the numerically calculated dispersion relation. This is clearly illustrated on the example of Si nanowires with different cross sections.NSF

Carrier Statistics  Temperature Effects
10 Aug 2010  Teaching Materials  Contributor(s): Saumitra Raj Mehrotra, Dragica Vasileska, Gerhard Klimeck
Silicon (Si), Germanium (Ge) and GalliumArsenide (GaAs) are commonly used materials for MOS Field Effect Transistor (MOSFET) fabrication. MOSFET structures are commonly doped to achieve the desired switching operation and doping is a critical parameter in MOSFET designing.
The goal in this test is to calculate the temperature range of device operation using Si,Ge and GaAs materials.

Carrier Statistics Tool Verification
10 Aug 2010  Teaching Materials  Contributor(s): Saumitra Raj Mehrotra, Dragica Vasileska, Gerhard Klimeck
This test verifies the Carrier Statistics Tool by comparing the numerically computed and analytically extracted, electron and hole carrier densities. The results are close within 2% of margin.

Computational Electronics
07 Jul 2008  Teaching Materials  Contributor(s): Dragica Vasileska, Gerhard Klimeck, Stephen M. Goodnick
As semiconductor feature sizes shrink into the nanometer scale regime, device behavior becomes increasingly complicated as new physical phenomena at short dimensions occur, and limitations in material properties are reached. In addition to the problems related to the actual operation of ultrasmall devices, the reduced feature sizes require more complicated and timeconsuming manufacturing processes. This fact signifies that a pure trialanderror approach to device optimization will become ...

Crystal Directions and Miller Indices
08 Jun 2010  Teaching Materials  Contributor(s): David K. Ferry, Dragica Vasileska, Gerhard Klimeck
Miller indices are a notation system in crystallography for planes and directions in crystal lattices. In particular, a family of lattice planes is determined by three integers, l, m, and n, the Miller indices. They are written (lmn) and denote planes orthogonal to a direction (l,m,n) in the basis of the reciprocal lattice vectors.
