SPM Aarhus 150 HT
Extremely Stable and Highly Versatile SPM Aarhus 150 SPECS for Ultimate High Temperature Scanning Probe Microscopy Applications
By adding a radiative heater element with a high stability power supply, the SPM Aarhus 150 allows imaging of all kinds of samples at temperatures exceeding 1300K (650K with KolibriSensor™). SPM Aarhus 150 HT can be used with both STM tips as well as with KolibriSensor™ without any compromises on its stability. Using improved heat flow management it is possible to suppress thermal drift with ultimate mechanical and thermal stability regardless of temperature and duration of the experiment. The instrument runs in the thermal steady-state condition meaning that sample is the only object that changes its temperature during operation. All other parts of the instrument stay at the constant temperature thus minimizing thermal drift. To achieve this a combination of permanent cooling and counter heating of the scanner platform is used. Special heaters are integrated on the scanner platform and on the scanner itself and are constantly regulated compensating changes in the power flow induced by the change of the sample temperature. Thus the scanner platform acts as a heat sink for the power flow from the hot sample to the scanner ensuring excellent thermal stability and uncompromised SPM performance. A direct in-situ optical access allows for the sample illumination and investigation of light induced processes. Additionally an evaporation port permits in-situ deposition and investigation of the growth processes during scanning.
