A new algorithm allows the fast reconstruction of atom distributions in 3D nanostructured surfaces

Over the last years, PTB has developed a new method for atom-specific reconstruction of periodically nanostructured surfaces. Recent studies have shown experimentally that it is possible to reconstruct and identify the spatial distribution of different atomic species in nano-components using X-ray...

The DFG – project "Bayesian compressed sensing for nanoscale chemical mapping in the mid-infrared regime" has started at the beginning of this year. The project aims at the reduction of large amounts of data and measurement times in scanning probe-based spectroscopy with broadband infrared synchrotron radiation. Scanning probe techniques with their pixel-by-pixel data acquisition and conventional...
