Research Impact Statement:

Scanning probe microscopy has been the cornerstone of nanotechnology since the late 1980s. Scanning probe instruments allow the visualization and characterization of nanometer-scale objects with minimal sample preparation. The Hall Nanometrology Laboratory in the Birck Center is the home of a custom UHV scanning probe microscope system built around an Omicron STM and AFM. This instrument is primarily for atomic-scale imaging. The STM/AFM has been integrated into stainless steel chambers equipped with fast-entry load locks and a versatile sample preparation chamber which allows for thermal or ion gun cleaning of substrates, adlayer (either molecular or metals) deposition, and tip cleaning. The Hall Laboratory is a unique nanometrology laboratory designed and built to minimize unwanted building vibrations, maintain a constant temperature and shield equipment from stray EM fields.
