To assess the conversion and embedment of yttrium nitrate to yttrium oxide using selective laser melting, a thermodynamic approach for laser power and scan speed predictions on surface temperature, recoil pressure, and resulting track morphology window are employed. Inkjet printing is used to deposit the liquid film of yttrium nitrate...
Copper zinc tin sulfide (CZTS) is a potential solar material for thin film solar cells according to its suitable band gap in the visible light range, high absorption coefficient, low toxicity, good photostability and relative earth abundance of component elements. However, the production cost of this solar thin film material...
Recent advances in nanocrystalline materials production are expected to impact the development of next generation low-cost and/or high efficiency solar cells. For example, semiconductor nanocrystal inks are used to lower the fabrication cost of the absorber layers of the solar cells. In addition, some quantum confined nanocrystals display electron-hole pair...
A unique microreactor-assisted nanomaterial synthesis and printing process was studied for the fabrication of patterned metal oxide nanostructured thin films. The process uses a continuous flow microreactor to control and generate a reactive chemical flux that was transported to a patterned microfluidic channel. The microreactor-assisted nanomaterial synthesis process can generate...
The critical contribution of this dissertation is to provide a better
understanding of the fundamental Chemical Bath Deposition (CBD) growth
kinetic and mechanism for the well known II-VI semiconductor CdS using the

provides the temporal resolution to control the homogeneous reaction...
As a group of promising semiconductor materials, metal chalcogenides in thin film form have been widely used in electronics and optoelectronics applications, such as solar cell devices and photon sensors. Unfortunately, the film size and product throughput are limited by the current vacuum-based thin film deposition techniques. Solution-based thin film...
The various solution-based processes, spin coating, inkjet printing, microreactor assisted nanoparticle deposition (MANDTM) and spin-successive ionic layer absorption and reaction (Spin-SILAR) were used to demonstrate thin film electronics and anti-reflective coatings. Several aspects of thin film transistors (TFTs) were tested including a range of temperatures, annealing atmosphere, and deposition methods....
Metal oxide nanocrystals have attracted significant interests due to their unique chemical, physical, and electrical properties which depend on their size and structure. In this study, a continuous flow microreactor system was employed to synthesize metal oxide nanocrystals in aqueous solution. Assembly of nanocrystals is considered one of the most...
Metal-Organic Frameworks (MOFs) are crystalline compounds formed from reacting a metal ion with an organic ligand. They represent a promising new avenue in materials science for gas separations and storage. Certain MOFs, in particular Mg-MOF-74, have shown a strong affinity for the capture of CO2. This project investigated a known...
