LT-STM System

SPS-CREATEC GmbH is a subsidary of Createc Fischer & Co. GmbH. It was established in 2003 to develop, build and service scanning probe microscopes. The company managed by Albrecht Fischer and Dr. Sven Zöphel has its offices in the new CreaTec Building in Erligheim (near Stuttgart), Germany.
Our LT-STM was developed with Dr. Gerhard Meyer during the PhD thesis of Sven Zöphel at the FU Berlin in the group of Prof. K.-H. Rieder. Following the demand of our customers we are continuously developing this instrument. It is very well known for it's outstanding stability and performance in the scientific community.

The LT-STM is specially designed for working at atomic scale at low temperature (i.e. to perform atomic / molecular manipulation or local spectroscopy). The STM has a modified Besocke beetle design which ensures its high stability (dz<1pm) and only a small drift.


STM-Overview

  • High stability Besocke beetle type STM
  • Very small drift at low temperature: <2Å/h in thermal equilibrium
  • Temperature variable: 6-300K
  • Optional pumping of the LHe cryostat for temperatures below 4K
  • Very low helium consumption: 4 litres in 48 hours guaranteed (up to 100h achieved!)
  • Optical access to the tunnelling junction
  • 6 electrical contacts to the sample in the STM
  • Sample transfer at low temperatures
  • Magnetic tip transfer system
  • Scan range: 1µm x 1µm x 0.2µm @ 6K
  • Clean ‘in situ’ dosing or evaporation
  • Powerful software with spectroscopy and nanostructuring support
