On the Properties and Characteristics of Solution Processed Hafnium Based Thin-Films from Aqueous Precursors

Creator:

Decker, Shawn R.

Abstract:

Aqueous hydroxo Hf nanoclusters enable studies to identify and codify steps in the deposition of Hf-based oxide thin films from solution precursors. HfOCl2 reacts with combinations of H2O2(aq), acids, and TMAH to produce polymetal species at high pH and low pH. X-ray scattering and spectroscopic methods reveal the nature of...

Metal-oxo Clusters as Novel Photolithographic Materials: How Understanding the Chemistry of HafSOx Informs Next-Generation Patterning Systems

Creator:

Amador, Jenn M.

Abstract:

The solution chemistry and kinetic behavior of hafnium peroxy sulfate solutions ("HafSOx") is described in terms of peroxide content and solution speciation. Additionally, thin film behavior, including thermal behavior and solubility, is characterized, and a mechanism of patterning is presented, as well as parameters that should be considered when looking...

New multi-functional chalcogenides for photovoltaic and thermoelectric materials

Creator:

Heo, Jaeseok

Abstract:

The subject of this PhD thesis is part of a research domain of great present interest in new semiconductor materials for photovoltaic and thermoelectric applications. This domain contains the elaboration and the study of both Cu-based chalcogenides bulk and thin-film samples, driven by materials design principles. One of the most...
