The Electronic and Structural Properties of Semiconductor Clusters and Nanostructures

In this Chapter. I will review theoretical research on nanostructured matter performed at the University of Minnesota. My emphasis will be on pseudopotential methods which are implemented in real space. This approach allows one to examine systems which heretofore were inaccessible by ab initio methods. Illustrations of these methods will focus on clusters composed of semiconducting materials (Si, Ge and GaAs) and Si quantum dots. Comparisons will be made to recent photoemission, Raman, polarizability, and optical absorption measurements.
