Book Description
This thesis focuses on the design and synthesis of novel one-dimensional colloidal chalcogenide hetero-nanostructures for enhancing solar energy conversion applications. Semiconducting nanomaterials are particular attractive for energy conversion due to the quantum confinement effects dictating their unique optical and electronic properties. Steering the photo-induced charge-flow based on unique bandgap alignment in semiconductor heterojunctions is critical for photo-electric/chemical conversion. The author presents the controllable preparation strategies to synthesize 1D chalcogenide hetero-nanostructures with various fine structures, further been used as excellent template materials for preparing other novel and complex hybrid architectures through a series of chemical transformations. The heterogeneous growth mechanisms of novel hetero-nanostructures is studied for developing a facile and general method to prepare more novel heterostructures. The band gap structure simulations, detailed charge carrier behaviour and unique solar energy conversion properties of the prepared hybrid nanostructures are deeply investigated. This work would open a new door to rationally designing hybrid systems for photo-induced applications.

Book Description
Semiconducting nanoscale metal chaicogenides are an important class of materials used in optoelectronics, photovoltaics, and thermoelectric applications. The properties of nanomaterials are directly influenced by their size and shape. Because of this a great deal of research has been focused on the size-controllable synthesis of these materials. Metal chalcogenide nanomaterial:; have been synthesized using solvothermal, sonochemical, pyrolysis, and microwave heating methods, which require high temperature and pressure. Furthermore, the reactants, solvents, and reaction conditions are highly specific for each method as well as the desired nanomaterial.

Book Description
Metal chalcogenides is a large family of functional materials with rich physical and chemical properties depending on their compositions, dimensions and phases. They have a broad range of applications in electronics, optoelectronics and energy conversion/ storage. The possibility to prepare these materials into low-dimensional nanostructures may allow the access to novel properties that are absent in their bulk counterparts. Such a development, however, requires a reliable approach to controllably synthesize chalcogenides into nanostructures. Here, we primarily employ a horizontal tube furnace reactor to grow such chalcogenide nanomaterials. These nanostructures serve as a material platform to expand the applications of this family of materials towards new areas. We first describe the opportunity to study topological insulator electronic properties in several chalcogenide materials. Topological insulators are narrow-gap semiconductors with metallic electronic states that are always present at their surfaces. The unique property associated with such surface carrier is that the spin direction is determined by its moving direction. The unusual spin texture gives rise to many unusual physical properties. Several chalcogenides are identified as topological insulators based on theoretical calculations and spectroscopic measurements. However, there are many challenges to make use of their exotic properties in electrical measurements. We propose topological insulator nanostructures, with large surface-to-volume ratio, enhance the surface properties in electron transport process. Our systematic transport measurements reveal the signature of the surface carriers on nanostructures of these chalcogenides. Combined with detailed structural and compositional analyses, our studies addressed some material challenges to probe and access the surface electronic properties on these chalcogenide topological insulators. Some chalcogenide nanomaterials also serve as attractive electrocatalysts for water splitting. With the interest to use hydrogen as a sustainable and carbon-free energy carrier, it is attractive to explore and optimize catalyst materials suitable for electrochemical water reduction. Certain layered dichalcogenides, such as MoS2 and WS2, are chemically active electrocatalysts for hydrogen evolution reaction (HER), with the promise to replace noble metal catalysts like Pt. Previous studies have identified the edges of the molecular layers are catalytically active, which opens up a rational pathway to boost the activity by increasing the exposed edge sites. We developed a synthesis technique to produce edge-rich thin films and nanostructures. The structural engineering and further chemical doping process allow us to access novel MoS2 catalyst with high activity for HER. In addition, we also identified a new group of first-row transition metal dichalcogenides (ME2, M = Fe, Co, Ni ; E = S, Se) catalytically active towards HER. These catalysts exhibit excellent activity and stablilty that expand the family of non-precious HER catalysts.

Book Description
A novel synthesis technique for the production of copper zinc tin sulfide (CZTS) nanocrystals has been developed using aerosol spray pyrolysis. CZTS is a quaternary semiconducting material that shows promise as a replacement to common semiconductors such as CdTe and CIGS for use in photovoltaic devices. CIGS is currently being commercialized in the photovoltaic industry, but rare and expensive indium and gallium components threaten its long term viability. CZTS looks to be one of the best alternatives to CIGS with all earth abundant and non-toxic materials and recent impressive gains in efficiency. A number of synthesis techniques have been thoroughly studied and detailed previously. In our novel approach, we synthesis single phase nanocrystals, starting with zinc, copper, and tin diethyldithiocarbamate precursors in a toluene solvent. The precursor solution is aerosolized using an ultrasonic nebulizer wherein the droplets are vacuumed through a tube furnace and nucleation occurs. We reproducibly synthesize kesterite, Cu2ZnSnS4, nanocrystals. This technique continuously converts the chemical precursor into high-purity nanopowder with a production rate of ~50 mg/hour for an un-optimized, lab-scale reactor. Using the same precursor chemistry, we have also been able to deposit high-quality CZTS thin films directly onto Mo-coated Swiss glass substrates using the aerosol spray pyrolysis technique. A thorough discussion of the current photovoltaic field, the processing parameters and challenges of nanocrystal and thin film production, and the experimental results will be presented. Characterization via Raman spectroscopy, EDS, XRD, TEM and XPS will be offered along with future recommendations and considerations.
