LT-STM / AFM
A Leader for 25 years
The low-temperature scanning tunneling microscope (LT-STM) has been a core offering since 2000. Operating at temperatures from 4 to 300 K, three distinct systems are available: the 4 K LT-STM, the 4 K LT-STM/AFM unit, and the 1 K LT-STM. Each offers exceptional spectroscopic capabilities and enables precise atom and molecule manipulation.
A reliable workhorse so you can focus on results
With 25 years of proven reliability, the variable temperature range of 5 to 300 K enables a wide range of experiments. AFM integration, introduced in 2007, allows simultaneous force and tunneling current measurements for comprehensive surface characterization.
Tailored Precision for Your Specific Demands
Customizable 4 K microscopes are available in beetle-type and PAN-type configurations. Features include magnetic field, optical access, and high-frequency cabling. Applications span STM, STS, and IETS analyses across materials from metals to superconductors.
Let the data speak for itself
STS
Minimal modulation (less than microV) bypasses modulation effects. Temperature plays a crucial role in energy resolution, enabling precise spectroscopic measurements.
STM
Achieves genuine atomic resolution (2 pm), demonstrates herringbone patterns (20 pm), and shows superimposed standing waves on metal surfaces.
AFM
Non-contact AFM (nc-AFM) capability works on both conductive and insulating surfaces. Uses qPlus sensors with decorated tips (Xe or CO) for submolecular resolution imaging.
