WebOther articles where allowed band is discussed: band theory: …in a solid are called allowed bands. Certain ranges of energies between two such allowed bands are called forbidden bands—i.e., electrons within the solid may not possess these energies. The band theory accounts for many of the electrical and thermal properties of solids and forms the basis … Websimilar to that used by S.L. Altmann (Band theory of metals: the elements, Pergamon Press, Oxford, 1970). This book is very useful in our understanding the concept of the Bloch theorem. The eigenvalue problems are solved, depending on the strength of the periodic potential (we use Mathematica 5.2 to solve the problems).
