The Kronig-Penney model is a model used to study properties of electrons confined in a periodic potential. It is a useful model since the electronic properties can be studied analytically with the aid of Bloch's theorem. An important concept that emerges from the resultant electron band theory is the electron effective mass. Through the use of the Kronig-Penney model we use the so-called ...Kronig-Penney Model. Learn more about kronig_penney_model Can anyone provide me the MATLAB code for Kronig-Penney model to draw band structure for 1-D periodic potential well structure?The Kronig–Penney model (named after Ralph Kronig and William Penney [2]) is a simple, idealized quantum-mechanical system that consists of an infinite periodic array of rectangular potential barriers . The potential function is approximated by a rectangular potential:

A simple model for a solid is to consider the ID potential below to be the potential from the fixed ions, and then find the wave functions and energies of an electron in this potential. This is a very rough model for the potential from the ions, but it still captures the important behavior. This model is called the Kronig. Penney model.The Kronig-Penney model is quite useful for illustrating many important features of the quantum behaviour of electrons in periodic lattice. Although the Kronig-Penney model is well‐known and has been discussed in solid state textbooks, we try to use a simple and accessible way without the extremely laborious and tedious algebra evaluation to solve Kronig-Penney model. This paper ...The Kronig-Penney model is a 1D system that demonstrates band gaps, which relate to the allowed energies for electrons in a material. In this tutorial we calculate the bandstructure for Kronig-Penney Model.
