  2. ABACUS Exercise: Bandstructure – Kronig-Penney Model and Tight-Binding Exercise

    20 Jul 2010 | | Contributor(s):: Dragica Vasileska, Gerhard Klimeck

    The objective of this exercise is to start with the simple Kronig-Penney 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...

  3. 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 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...

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

    27 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...

    09 Sep 2009 | | Contributor(s):: Ron Reifenberger

    Note: This lecture has been revised since its original presentation.Topics:Electron States in Solids – Bloch FunctionsKronig-Penney ModelDensity of States

  6. 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...

  7. Periodic Potential Lab Demonstration: Standard Kroenig-Penney 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...

  8. Periodic Potential Lab: First-Time User Guide

    07 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...
