  1. 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 self-learning 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...

  2. 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...

  3. 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 non-derivative methods are discussed, as well as the importance of the starting guess and how to find or generate good initial structures. We also briefly...

  4. Cosine Bands: an Exercise for PCPBT

    21 Aug 2008 | | Contributor(s):: Gerhard Klimeck, Dragica Vasileska

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

  5. Periodic Potential Lab

    19 Jan 2008 | | Contributor(s):: Abhijeet Paul, Junzhe Geng, Gerhard Klimeck

    Solve the time independent schrodinger eqn. for arbitrary periodic potentials

  6. Periodic Potential Lab Demonstration: Standard Kroenig-Penney Model

    03 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...

  7. Periodic Potential Lab: First-Time User Guide

    05 Jun 2009 | | Contributor(s):: Abhijeet Paul, Benjamin P Haley, Gerhard Klimeck, SungGeun Kim, Lynn Zentner

    This document provides guidance to first-time 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...

  8. 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 one-dimensional crystal are performed with the Kronig-Penney (KP) model. This model has an analytical solution and therefore allows for simple calculations. More realistic models always require extensive numeric...

  9. 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...
