Abstract
The density of states in crystalline and amorphous germanium are obtained directly from 47-atom-cluster calculations using the extended Hückel theory (EHT), with the specific intention of comparing the changes in their characteristics as Ge takes on these forms. Diamond lattice is assumed in the crystalline cluster. The Henderson-Herman and the Polk-Boudreaux model coordinates are used in amorphous Ge. Observed changes in the density of states are discussed and compared with previous studies. EHT proves to be a simple and practical method in the study of disordered systems.Keywords
