Multimodal Chemical Imaging for Physical and Chemical Characterization

The functionality of materials is largely determined by the mechanisms that take place at sub-micron length scales and at interfaces. In order to understand these complex material systems and further improve them, it is necessary to measure and map variations in properties and functionality at the relevant physical, chemical, and temporal length scales. The goal of multimodal imaging is to transcend the existing analytical capabilities for nanometer scale spatially resolved material characterization at interfaces through a unique merger of advanced microscopy, scanning probe microscopy, mass spectrometry and optical spectroscopy, this merger is rooted in innovative data processing algorithms and techniques. In particular I will talk about instrumentation developments for multimodal chemical imaging on a combined Helium Ion Microscope (HIM) – Secondary Ion Mass Spectrometer (SIMS) and how to visualize material transformations at interfaces, to correlate these changes with chemical composition, and to distill key performance-centric material parameters using a multimodal chemical imaging.
