Ultra-Low-Temperature (1.1 K) Ultra-High-Vacuum Scanning Tunneling and Atomic Force Microscope (STM-AFM). The system has a 3T axial Magnetic Field and allows for in-situ atomic and molecular deposition at low temperature (< 5 K). The system is also equipped with a preparation chamber with the standard UHV tools and as well as an additional MBE chamber for ultra-clean sample growth. It is used for atomic manipulation, atomic and molecular magnetism studies, and research on physics at surfaces of functional materials.
