Resource Type:: Dissertation
Full Text:: AN ABSTRACT OF THE THESIS OF Dong Li for the degree of Doctor

Synthesis and study of oxides and chalcogenides : thin films and crystals

Creator:: Park, Sangmoon
Abstract:: Several types of solid-state inorganic materials are prepared and characterized. By using the SILAR (Successive Ionic Layer Adsorption and Reaction) deposition method in conjunction with hydrothermal dehydration both low-temperature deposition and crystallization of oxide thin films are achieved. Various aspects of new transparent p-type materials are studied by examining both...

Copper and iron chalcogenides for efficient solar absorption

Creator:: Platt, Heather A. S.
Abstract:: This dissertation outlines two approaches for improving the efficiency and reducing the cost of photovoltaic energy generation. First, the structures of known binary copper and iron compounds are used to choose the promising compositions Fe₂XS₄ (X = Si, Ge), Cu₃TaQ₄ (Q = Se, Te), and BaCuQ'F (Q' = S, Se,...

Refractory Amorphous Metal Thin Films

Creator:: Olsen, Kristopher R.
Abstract:: Amorphous metal thin films lack the grain boundaries and dislocations present in crystalline metal films. As a result, amorphous metal films can be more mechanically robust, atomically smooth, and more resistant to chemical attack than crystalline metals. However, amorphous metals are meta-stable and subject to crystallization upon heating, thus limiting...

New multi-functional chalcogenides for photovoltaic and thermoelectric materials

Creator:: Heo, Jaeseok
Abstract:: The subject of this PhD thesis is part of a research domain of great present interest in new semiconductor materials for photovoltaic and thermoelectric applications. This domain contains the elaboration and the study of both Cu-based chalcogenides bulk and thin-film samples, driven by materials design principles. One of the most...

Synthesis and study of transparent p- and n-type semiconductors and luminescent materials

Creator:: Park, Cheol-Hee
Abstract:: New transparent p- and n-type semiconductors and luminescent materials have been prepared and characterized. Synthesis, structures, optical and electrical properties of new chalcogenide fluoride p-type transparent semiconductors MCuQF (M=Ba, Sr; Q=S, Se, Te) are described. Band-gap tuning and improvement in conductivity through p-type doping are demonstrated in the family. The...

New luminescent materials and high-performance solution-processed oxide thin films

Creator:: Jiang, Kai
Abstract:: Crystals of an incongruent-melting compound, Ba₃MgSi₂O₈, were grown by the flux method and its structure was determined by single crystal X-ray diffraction methods. Ba₃MgSi₂O₈ crystallizes in trigonal space group P-3[bar]m1 with a = 5.6123(3) Å, c = 7.2667(9) Å and Z = 1. Eu²⁺ ions prefer one crystallographic Ba site...

Transition metal solar absorbers

Creator:: Altschul, Emmeline Beth
Abstract:: A new approach to the discovery of high absorbing semiconductors for solar cells was taken by working under a set of design principles and taking a systemic methodology. Three transition metal chalcogenides at varying states of development were evaluated within this framework. Iron pyrite (FeS₂) is well known to demonstrate...
