Properties of periodic continued fractions are used to find the dispersion relation inside allowed bands. The Mathieu potential is considered and it is found that relativistic effects cause a reduction of the width of allowed bands and gaps.engjournal articlehttp://iopscience.iop.org/0305-4470/24/7/004http://iopscience.iop.orgrestricted access538.9Kronig-Penney ModelFísica de materiales
