The separation between the conduction band and valence band on the energy band diagram is known as the forbidden energy gap (band-gap, E g ). The width of the energy gap is a measure of the bondage of valence electrons to the atom. The greater the energy gap, the more tightly the valence electrons are bound to the nucleus.Mathematical Solution of Kronig-Penney Model Determinant. 2020, International Journal for Research in Applied Science & Engineering Technology. Kronig Penny model is an excellent approximation of crystal potential in the band theory of solids. The only problem students face in this topic is the solving of determinant.

Kronig Penney model : According to Kroning and Penney the electrons move in a periodic square well potential. This potential is produced by the positive ions (ionized atoms) in the latce. The potential is zero near to the nucleus of positive ions and maximum between the adjacent nuclei.Condensed Matter Physics: Lecture 7 (Normal) In the last lecture we encountered the Kronig-Penney model, a simple onedimensional system in which the Schrdinger equation contains a periodic square-well potential. While you are familiar with the solutions of the individual square-well potential, the periodic case is significantly different. Todays …
