Variable Temperature UHV STM/AFM

The Omicron variable temperature ultra-high vacuum (UHV) scanning tunneling microscope (VTSTM) is designed to study the structure of both clean and adsorbate-covered solid surfaces. As a real space probe, emphasis is placed on examining defect structures and understanding their role in heterogeneous chemical processes. Sample temperatures during imaging can nominally range from 30 K to 1500 K. At low temperatures, even weakly bound adsorbates can be imaged due to the reduced thermal diffusion.
