Investigating relationships between physical structure and chemical functionality at the nanoscale through the development of multimodal imaging platforms; coregistration of multidimensional data, local tuning of material properties at interfaces using ion beams; in-situ helium ion microscopy for direct-write nanomanufacturing.
1. Local tuning of chemical functionality in materials. Engineering control in functional materials using helium and neon ion beams; investigating relationships between physical structure and chemical functionality through local tuning of material properties using a scanning helium ion microscope, probing the resultant material functionality using advanced scanning probe and optical spectroscopy; development of in-situ helium ion microscopy to understand influence of local structure on chemical dynamics and ion beam interactions.
2. Multimodal chemical imaging techniques. Development of multimodal imaging platforms for probing chemical and physical makeup and dynamic processes ongoing at interfaces. Linking structural information obtained via chemical imaging with other spectroscopic data to provide a direct correlation between chemical composition and material functionality.
