LT-STM

Since October 2008, we are operating an Omicron UHV LT-STM. The instrument offers combined STM/AFM capabilities in the temperature range of 3–350 K and a base pressure of 10-11 mBar at room temperature. Besides scanning probes, sample surfaces can be analysed chemically by XPS and structurally by LEED and RHEED. The system is further equipped with a range of evaporators, both on the STM and preparation chamber, a hydrogen cracker, and an ion gun.
