Atomic Layer Deposition (ALD) Process Development of Nb-doped TiO₂ as a Transparent Conducting Oxide (TCO) and ALD of HfO₂/Nb₂O₅ Bilayers as Insulating Barriers for Metal/Insulator/Insulator/Metal (MIIM) Diodes

Creator:: Lin, Shijia
Abstract:: Transparent conductive oxides (TCOs), primarily indium doped tin oxide, have been widely used in numerous fields since decades ago, such as solar cells, displays, OLEDs and ‘smart windows’ etc. Owing to the scarcity of indium, there is a great demand for new alternative materials. Metal/insulator/metal (MIM) diodes are a critical...

Using Computational Studies to Characterize Aqueous Metal Clusters : From Spectroscopy to Stability

Creator:: Wills, Lindsay A.
Abstract:: In this dissertation, the spectroscopic properties and thermodynamic stability of a class of materials known as metal oxo and hydroxo clusters are studied. In aqueous solutions, many metals can aggregate into discrete clusters of metals bridged by oxo or hydroxo ligands. These clusters are of particular interest to us for...

Refractory Amorphous Metal Thin Films

Creator:: Olsen, Kristopher R.
Abstract:: Amorphous metal thin films lack the grain boundaries and dislocations present in crystalline metal films. As a result, amorphous metal films can be more mechanically robust, atomically smooth, and more resistant to chemical attack than crystalline metals. However, amorphous metals are meta-stable and subject to crystallization upon heating, thus limiting...

Photoresist and ion-exchange chemistry of HafSOx

Creator:: Telecky, Alan J.
Abstract:: The chemistry of hafnium oxide based and materials are described in the context of ion exchange and lithography. HafSOx, represented by the composition HfO₂₋[subscript x](SO₄)x, is described to possess a significant capacity towards ion exchange in acidic and basic solutions, enabling films of HafSOx to be cleanly and readily be...

Investigation of metal-insulator-metal (MIM) and nanolaminate barrier MIIM tunnel devices fabricated via atomic layer deposition

Creator:: Alimardani, Nasir
Abstract:: Metal-insulator-metal (MIM) tunnel devices have been proposed for high speed applications such as hot electron transistors, IR detectors, optical rectennas for IR energy harvesting, and backplanes for LCDs. The majority of these applications require highly asymmetric and non-linear current versus voltage (I-V) behavior at low applied voltages and ultra-high frequencies....

Reaction Pathways of Oxo-Hydroxo Group 5 Clusters to Metal Oxide Thin Films

Creator:: Mansergh, Ryan H.
Abstract:: Oxo-hydroxo Group 5 metal clusters are an untapped resource to study and advance aqueous solution processing of metal oxide thin films. The tetramethylammonium (TMA) hexatantalate salt (TMA6[H2Ta6O19]) yields dense Ta2O5 films (~95% of the bulk ß-Ta2O5 density) with atomically smooth surfaces (<4 Å root mean square surface roughness). This same...

Fabrication of a flexible glucose sensing catheter for human implantation

Creator:: Matthews, David J.
Abstract:: Flexible electronics processing techniques were applied to integrate a glucose sensor with a hormone-delivery catheter in order to create a cheap and minimally invasive method for patients with type 1 diabetes to continually monitor and control their blood sugar levels. Ultimately, this work intends to move toward the development of...

The chemistry and device applications of amorphous thin-film interfaces

Creator:: Knutson, Christopher C.
Abstract:: Solid-state amorphous materials show amazing promise in thin-film electronics. The interface-to-bulk ratio of thin films makes interfacial chemistries of these systems of utmost importance. Thin films of amorphous metals, dielectrics and semiconductors have novel chemistries that are not only based upon their elemental constituent makeup, but also based upon the...

Computational Investigations of Transition Metal Catalyses and Amorphous Metal Oxides : Accelerating Scientific Discovery Through Automation

Creator:: Mustard, Thomas J. L.
Abstract:: Automation of computational chemistry, while only an engineering feat, has the potential to accelerating computational research be removing all by the science. The work in this thesis mainly discusses fundamental understanding of complex chemical systems. What is not obvious are the numerous tasks necessary for this fundamental understanding. Under the...
