A number of analytical theories related to disordered systems have been developed based on two major themes: (1) charge transport in non-crystalline semiconductor systems where localized states play the main role in the underlying mechanisms; and (2) crystal nucleation in the presence of a strong electric field. In this dissertation, five research topics based on these themes are presented: (1) charge transport through non-crystalline junctions; (2) admittance characterization of semiconductor junctions; (3) 1/f noise in chalcogenide glasses; (4) electric field-induced nucleation switching in chalcogenide glass threshold switches (TS) and phase change memory (PCM); and (5) relaxation oscillations in PCM. Although the theories are quite general in nature, their practical implications are discussed in the context of thin-film photovoltaics (PV), and chalcogenide glass TS and PCM. It is shown that, even at practical temperatures, hopping conduction via opti-mum channels of localized states can be the prevailing charge transport mechanism in semiconductor junctions. That type of transport results in laterally nonuniform current flow that leads to shunting, device degradation, and variations between iden- |
