Further
experiments, e.g. for the detection of work function differences, can
be added easily,
if an additional lockin amplifier is utilized.
The STM is provided complete with image
acquistion and image processing software.
As accessory, we provide a tip etching tool
for
tungsten tips based on a scientific publication.
The
tool is affordable, easy to handle and guaranties over 50 % usable
STM tips.
