attoSTM I
low temperature scanning tunneling microscope, highly stable and
compact
:.........................................................................................
The attoSTM I is a scanning tunneling microscope, designed particularly
for applications at low and ultra-low temperatures. The microscope
is manufactured exclusively of non-magnetic materials (predominantly
Titanium) enabling experimental setups using very low temperatures
and high magnetic fields.
To ensure ultra-low vibrations enabling
atomic resolution imaging, the complete system including cryostat
is vibration isolated.
Principle - The microscope uses a set of xyz positioners
for coarse positioning of the sample and the tip over several mm.
To achieve maximum stability, the xy and the z stage are separated
from each other. Furthermore, piezo tubes are implemented according
to the users requirements. Optical inspection of the tip/sample
is enabled via a CCD camera, an adjustable prism and an IR-LED
for illumination.
The exceptional combination of materials allows absolutely stable
atomic resolution imaging of surfaces.
