UHV Joule-Thomson low-temperature STM

 

Our newest microscope is a Specs Joule-Thomson UHV STM with base temperature of about 1K. The hold time for liquid helium is more than 100 hours which allows us to run experiments over long time. We use Nanonis SPM controller package to operate the microscope. The UHV system with base pressure in 10-11 mbar region is equipped with a wide choice of in-situ surface preparation techniques (ion gun, anneling stage, knudsen evaporators and effusion cell) and chemical (Auger electron spectroscopy (AES) and structural (low-energy electron diffraction (LEED)) characterization of the examined surfaces.
