ABACUS Exercise: Bandstructure – KronigPenney Model and TightBinding Exercise
20 Jul 2010   Contributor(s):: Dragica Vasileska, Gerhard Klimeck
The objective of this exercise is to start with the simple KronigPenney model and understand formations of bands and gaps in the dispersion relation that describes the motion of carriers in 1D periodic potentials. The second exercise examines the behavior of the bands at the Brillouin zone...

Comparison of PCPBT Lab and Periodic Potential Lab
04 Aug 2009   Contributor(s):: Abhijeet Paul, Samarth Agarwal, Gerhard Klimeck, Junzhe Geng
This small presentation provides information about the comparison performed for quantum wells made of GaAs and InAs in two different tools. This has been done to benchmark the results from completely two different sets of tools and validate the obtained results. In this presentation we provide...

Nanoelectronic Modeling Lecture 14: Open 1D Systems  Formation of Bandstructure
25 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...

Periodic Potential Lab: FirstTime User Guide
05 Jun 2009   Contributor(s):: Abhijeet Paul, Benjamin P Haley, Gerhard Klimeck, SungGeun Kim, Lynn Zentner
This document provides guidance to firsttime users of the Periodic Potential Lab tool. It offers basic information about solutions to the Schröedinger Equation in case of periodic potential in 1 dimension (1D). This document also contains suggested exercises to help users run the tool and...

Periodic Potentials and the KronigPenney Model
01 Jul 2008   Contributor(s):: Dragica Vasileska
This material describes the derivation of the KronigPenney model for deltafunction periodic potentials.

Periodic Potentials Exercise
15 Jun 2010   Contributor(s):: Gerhard Klimeck, Parijat Sengupta, Dragica Vasileska
In this exercise, various calculations of the electronic band structure of a onedimensional crystal are performed with the KronigPenney (KP) model. This model has an analytical solution and therefore allows for simple calculations. More realistic models always require extensive numeric...

Semiconductor Device Education Material
28 Jan 2008   Contributor(s):: Gerhard Klimeck
This page has moved to "a Wiki page format" When we hear the words, 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...
