Variable Temperature Scanning Tunneling Microscope

Variable Temperature Scanning Tunneling Microscope

Our "workhorse" is an Omicron VT-UHV-STM 50 K, which has been (and still is being) modified and optimized in our group for years. It is our original self-developed scanning thermal microscope (SThM) based on the commercial device.
