In the scope of this master thesis, a home-made brass scanning tunneling microscope
(STM) was machined, assembled and tested for its functionality. For
this microscope, a new approach-technique was used which follows the design suggested
by Pan. The difference to Pan's design is the use of piezoplates, instead of
piezostacks. Hence, the approach is still based on the stick and slip motion, but it
allows the microscope to be more compact. A new and simple electronic circuit,
in order to control the approach, is presented and was put together. This circuit is
based on mechanical relays, which provide a sufficient long time gap between the
single moving steps, due to their mechanical functional principle. Subsequently the
approach-technique and the scanning was successfully tested. Finally, first images
of HOPG were taken under ambient conditions. / text
