Modern Physics for Engineers Lecture slides 15a – Band structures

This lecture part illustrates how a simple band structure is built up by solving for the energies at each of a set of k (wavevector) values. It shows the concept of a Brillouin zone - the range of k required to represent a band structure - as well as concepts like a band gap energy between two bands, and the extended zone scheme, which shows the band structure just repeats for other values of k.
