Facilities

The Atomic Scale Physics research group is located in Nanotalo. The building also houses the Nanomicroscopy Center (NMC).

Our group operates two low-temperature, ultra-high vacuum (UHV), scanning probe microscopes.

 

Createc LT-STM/AFM

Createc.jpgThe Createc LT-STM/AFM operates at a low temperature (T = 5 K) and it is equipped with a quartz tuning fork force sensor (QPlus configuration) for simultaneous AFM and STM on the same atomic location at low tip oscillation amplitudes (A < 50 pm). Long hold time at the base temperature enables demanding experiments on measuring the spatially resolved local density of states and force landscapes.

The instrument has optical access to the tip-substrate junction and in situ evaporation to the cold sample. In addition, the instrument is equipped with a preparation chamber with standard sample preparation facilities (sputtering, annealing, evaporation).

 

Unisoku USM-1300

The Unisoku USM-1300 is designed for temperatures down to 300 mK and ultra-high vacuum to perform STM and spin-polarized STM experiments in an external magnetic field of up to 11 T. In addition, the instrument is equipped with a preparation chamber with standard sample preparation facilities (sputtering, annealing, evaporation).
