In this thesis the author presents the results of extensive spectroscopy experiments beyond the bounds of each transition element to clarify the origins of characteristic spectral features and charge dynamics in charge-spin-orbital coupled phenomena in Mott-transition oxides. Several counterpart 3d transition-metal oxides were adopted as model systems suitable for examining the mechanisms involved, and their electronic structures were systematically investigated using three main spectroscopy methods. Comparative studies on the charge dynamics and Mott transition features of transition-metal oxides were performed: Charge dynamics and thermoelectricity in a typical Mott transition system La1−xSrxVO3, charge dynamics in a doped valence-bond solid system (Ti1−xVx)2O3 and in layered nickelates R2-xSrxNiO4 with charge-ordering instability are investigated thoroughly. The results obtained successfully provide a number of novel insights into the emergent phenomena near the Mott transition.

Effects of pressure and temperature on electrical conductivity and thermoelectric power of NiO, CoO, Fe2O3, and Cu2O were measured. The temperature dependence of conductivity and Seebeck coefficient in lithium doped NiO and CoO single crystals indicated that hole mobility was thermally activated with an activation energy of 0.1 ev. Hopping type transport appeared likely in these materials. The temperature dependence of electrical properties on pressure compacted titanium doped Fe2O3 also indicated that electron mobility was thermally activated. Electrical conductivity of Cu2O single crystals increased exponentially with temperature in the 300K to 500K range. The activation energy was 0.26 ev. The Seebeck coefficient was nearly constant, about 1 mv/deg. C from 300K to 500K. Hopping transport is a diffusion process and may have an associated heat of transport. If the heat of transport is not nearly zero, the usual equations for charge concentration and mobility in terms of resistivity and thermoelectric power are not correct. It can be shown that according to the Holstein hopping model the heat of transport should be nearly zero. Conclusions about charge carrier mobility from resistivity and thermoelectric power measurements should be nearly correct. (Author).

To fulfill the needs for developing the alternative energy technologies, searching for the adequate electrode materials which catalyze the electrochemical reactions utilized in devices such as fuel cell, Li-ion batteries, and related applications such as hydrogen generation and storage, has been a longstanding challenge. Among various catalysts, transition metal oxides (TMO) draw great attentions due to their low-cost, high stability, and, most importantly, a great variety of structures and electrical properties. Nonetheless, studying electrochemical reactions catalyzed by TMO is a challenging task due to the possible multivalent systems, flexible coordinations of lattice atoms, adjustable surface structures and diverse surface species. In the past decades, many innovative approaches have been explored with encouraging results; however, the mechanisms of incorporating the bulk/surface TMO structures in various chemical reactions still remain unclear. In this dissertation, using quantum mechanical calculations, we attempt to improve the fundamental understandings of how structures and electronic properties of TMO materials facilitate the electrochemical reactions of interest. To identify the possible causes for CuO and Cu structures having different selectivity in catalysis, in Chapter 3, we study the CO2 reduction reaction (CO2RR) catalyzed by CuO (111) surface structure, and compare the results with the more widely studied Cu (100) surface. The roles played by the electronic properties of two materials in their selectivity are elucidated. In Chapter 4 and 5, we study the oxygen evolution reaction (OER) for LiCoO2 surface structure. The structures and stabilities of Li-, O-, and H-terminated surface are investigated comprehensively. Based on the results, the formation of H-terminated surface results from Li/H exchange at the solid/liquid interface is proposed (Chapter 4). Along with the findings, we explore the possible mechanisms for the OER for non-metal terminated LiCoO2 surface (Chapter 5). In Chapter 6, we study the oxygen reduction reaction (ORR) for Co3O4 (111) H-terminated surface structure. The possible reaction steps for both four-electron and two-electron pathway are investigated. In Chapter 7, the PO4-decicient LiFePO4/FePO4 structures are investigated to understand how the presence of polyanion defects in the matrices could potentially improve the performance of the materials as electrodes in Li-ion batteries
