ABACUS: Test for Periodic Potential Lab
05 Aug 2010  Contributor(s):: Dragica Vasileska, Gerhard Klimeck
The objective of this test is to give an idea to a selflearning students or to instructors in the case this test is used in a classroom the level of understanding of this topic when students have gone through the learning material, worked exercises and have completed the assignments and the...

Periodic Potentials Exercise
16 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...

Comparison of PCPBT Lab and Periodic Potential Lab
10 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...

Periodic Potential Lab Demonstration: Standard KroenigPenney Model
11 Jun 2009   Contributor(s):: Gerhard Klimeck, Benjamin P Haley
This video shows the simulation of a 1D square well using the Periodic Potential Lab. The calculated output includes plots of the allowed energybands, a table of the band edges and band gaps, plots of reduced and expanded dispersion relations, and plots comparing the dispersion relations to...

Periodic Potential Lab: FirstTime User Guide
07 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...

Cosine Bands: an Exercise for PCPBT

This exercise demonstrates the formation of cosine bands as we increase the number of wells in the nwell structure.

Computational Nanoscience, Lecture 4: Geometry Optimization and Seeing What You're Doing
13 Feb 2008   Contributor(s):: Jeffrey C Grossman, Elif Ertekin
In this lecture, we discuss various methods for finding the ground state structure of a given system by minimizing its energy. Derivative and nonderivative methods are discussed, as well as the importance of the starting guess and how to find or generate good initial structures. We also briefly...
