Supercritical Fluid Deposition Of Thin Metal Films: Kinetics, Mechanics And Applications, Christos Fotios Karanikas
Supercritical Fluid Deposition Of Thin Metal Films: Kinetics, Mechanics And Applications, Christos Fotios Karanikas
Doctoral Dissertations 1896 - February 2014
In order to meet the demands of the continuous scaling of electronic devices, new technologies have been developed over the years. As we approach the newest levels of miniaturization, current technologies, such as physical vapor deposition and chemical vapor deposition, are reaching a limitation in their ability to successfully fabricate nano sized electronic devices.
Supercritical fluid deposition (SFD) is a demonstrated technology that provides excellent step coverage for the deposition of metals and metal oxides within narrow, high aspect ratio features. This technique shows the potential to satisfy the demands of integrated circuit miniaturization while maintaining a cost effective process …

Confining walls induce qualitative changes in adsorbed fluids. Among the most intriguing phenomena is hysteresis, where a pore fills with fluid at a greater pressure than it empties. The causes and mechanisms by which this occurs are intensely investigated yet still poorly understood. Ordered mesoporous silicas, recently discovered materials with well-defined pore size distributions, provide an opportunity to deepen our understanding of the fundamental physics of the interaction of fluids with complex solids.
In part of this computational investigation we examine idealized pores. In agreement with other recent studies, we find that in 'inkbottle'-shaped pores, where a large cavity is …

Microwave Reactor Engineering Of Zeolites Synthesis, Murad Gharibeh
Doctoral Dissertations 1896 - February 2014
Microwave chemistry has expanded over the last two decades due to the enhanced reaction rates achieved for many processes, including organic synthesis, inorganic synthesis and polymerization. Significant time and energy saving can be realized using microwave chemistry, which is important both commercially and for the environment.
One of the most exciting and commercially/technologically significant areas where microwave energy has been demonstrated to influence the kinetics and selectivity is in the synthesis of nanoporous materials, such as zeolites. New nanoporous materials can be created, and the times for their syntheses can be significantly reduced, involving using less energy. By reducing the …
