Probing localized states distributions in semiconductors by Laplace transform transient photocurrent spectroscopy
… is formulated in the context of the transient photoconductivity (TPC) experiment. A brief review of the existing mathematically approximate methods (Naito H. <i>et al</i>, 1996; Nagase T. <i>et al</i>, 1999; Ogawa N. <i>et al</i>, 2000) based on the <i>Laplace </i>transformation for …

On the design and synthesis of titanium dioxide-graphene nanocomposites for enhanced photovoltaic and photocatalytic performance
… The integration of graphene increased the photocurrent generated by the TiO2 in response to UV light tenfold. I attribute this enhancement to the ability of RGO to capture photogenerated electrons from TiO2 and conduct them efficiently to a conducting substrate: transient photocurrent …

TOWARD A BETTER CLEANING AND SELECTIVITY IN ELECTROANALYSIS: TIO2-BASED SENSORS AND ENANTIOSELECTIVE MATERIALS
… (EIS), atomic force microscopy (AFM) and transient photocurrent analysis. Once the study of the aging time of the sol was over, AuNPs were added to the device to form a heterojunction. This device was used for the detection of different emerging contaminants and the photocatalytic …

Role of Vacancies and Electrochemical Applications of Facet-Controlled Synthetic Superlattice Nanomaterials
… between types and concentration of vacancies and transient photocurrent properties were investigated. The first section of the thesis focuses on the synthesis of high performance noxious materials for CE of DSSCs. In the process, it was intially found that the zeta potential is one of the key …

Characterisation of molecular materials for electronic devices
… with steady state optical excitation, and transient excitation as a function of temperature, field, excitation intensity and excitation energy. It was found that in most experiments all oligomers yielded similar results, suggesting that the specific chemical structure of the oligomers is …
