Ferrites have been used for various high frequency applications as bulk
materials. These applications, however, are limited to large dimension devices. In
this thesis, thin film ferrites were deposited from a low temperature solution-based
deposition process that is suitable for micro-scale high frequency applications. The
low temperature nature of this...
Lanthanum sulfide film was deposited on silicon dioxide substrate by pumping aqueous
LaCl3∙7H2O and Na2S∙9H2O solutions into a T-mixer. After mixing, residence time was
manipulated to adjust lanthanum sulfide deposition rate. Lanthanum sulfide films were
created on silicon dioxide substrate at room temperature, 60 °C, and at 100 °C.
Lanthanum...
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
newly developed continuous flow microreactor. This continuous flow microreactor
provides the temporal resolution to control the homogeneous reaction...
The focus of this study is to develop a general and low-cost solution-based
process to fabricate micro- and nano-structured semiconductors that are suitable
for electronics. This process uses simple metal halide precursors dissolved in a
solvent (organic or aqueous) and is capable of forming uniform and continuous
thin films via...
Over the years, chemical bath deposition (CBD) is being widely used in the fabrication of Cu (In, Ga) Se₂ and CdTe based solar cells and photovoltaics. Many chalcogenides have been successfully deposited by this technique and it has received a great deal of attention owing to its low temperature and...
Marine diatoms are a class of microalgae that possess cell walls composed of silica nanoparticles. These organisms actively assimilate silicic acid Si(OH)4 from seawater, polymerize silicic acid to silica nanoparticles by a protein-mediated precipitation process, and then assemble the silica nanoparticles into intricate patterns that constitute the cell wall microarchitecture...
Copper sulfides (Cu[subscript x]S) are compound semiconductor materials that exhibit considerable optical and electrical properties varying significantly as a function of the composition. Copper sulfide thin films can be used in many applications, such as solar control coatings, solar cells, photothermal conversion of solar energy, electroconductive coatings, and microwave shielding...
