Level of Access
A state-of-the-art advanced materials synthesis and processing facility focusing on the growth and fabrication of ceramic- based thin film materials will be funded with the assistance of the Academic Research Infrastructure Program. The facility will include a multi-technique thin film materials synthesis chamber equipped with a microwave plasma source, effusion cells, electron beam evaporators, magnetron sputter sources, and a Kauffman ion source. Characterization capabilities will include in-situ reflection high energy electron diffraction (RHEED), mass spectrometry for controlling growth processes, X-ray photoelectron spectroscopy (XPS), and a novel Hall probe for in- situ film characterization. Three major areas of research will be impacted significantly by the facility, namely 1) solid state micro-sensors, 2) nanomechanics of materials, and 3) surfaces and interfaces in hetero-epitaxial oxide systems. In the sensor work, which has connections with local industry, the synthesis and processing of well-defined doped metal-oxide films will be developed with the goal of understanding and controlling the molecular scale mechanisms by which surface microstructure, dopant type, and operating temperature influence sensor performance. A broad based advanced materials synthesis and processing facility for the growth and fabrication of ceramic-based thin films will be operated for the study of solid state microsensors based on metal-oxide ceramic films. The nanomechanics of these ceramic thin films will be studied, as well as the surfaces and interfaces occurring in heteroepitaxial oxide systems.
