What is your thesis topic?
I am conducting experiments evaluating uranium dioxide for use as a material in solid-state direct-conversion neutron detection. In addition to materials processing, neutron irradiation studies have been performed on bulk and thin film samples.

How is materials processing involved in your research?
My research involves evaluating UO2 as a potential semiconductor for use in solid-state neutron detectors. The required material properties of uranium oxides do not inherently meet the goals required for these devices. Utilizing different processing methods can improve these properties by the introduction of dopant materials to alter the microstructure and electrical properties.

Provide an example of where the material/process/properties you are studying might find an application.
The current goal is to improve the properties of the candidate material’s to match the required electrical properties of solid-state neutron detectors. This requires increasing the electrical resistivity and carrier mobility and depends on utilizing various processing methods.
