We model, in an elementary way, the excited electronic states of semiconductor crystallites sufficiently small (∼ 50 A diam) that the electronic properties differ from those of bulk materials. In this limit the excited states and ionization processes assume a molecular-like character. However, diffraction of bonding electrons by the periodic lattice potential remains of paramount importance in the crystallite electronic structure. Schrodinger's equation is solved at the same level of…

A simple model for the ionization potential, electron affinity, and aqueous redox potentials of small semiconductor crystallites

Large semiconductor crystals have intrinsic electronic properties dependent upon the bulk band structure. As the crystal becomes small, a new regime is entered in which the electronic properties
