Deposition and Microfabrication
Physical structures ranging in size from miniature objects (nanomaterials) to electrical devices (thin films) with planned properties can be made using the deposition and microfabrication capability. Materials with specific surface, bulk and interfacial properties for energy and environmental applications can be designed and made using these integrated capabilities. See a complete list of Deposition and Microfabrication instruments.
Resources and Techniques
- Functionalized surfaces – Design and manufacture surfaces optimized for specific functions related to catalysis and other areas.
- Model systems for geochemistry/biogeochemistry – Grow model oxide and mineral films with varying structure and complexity.
- Materials with designed properties – Film growth and ion implantation for materials with specific properties.
- Chemical and biological sensing – Film and surface layer deposition and modification, micro and nano-lithography, and solution synthesis capabilities.
- Microfabrication – Engineering, software development and fabrication are used to design and fabricate next-generation components.
