Abstract
We report on the direct observation by means of low
temperature scanning tunneling microscopy and spectroscopy (STM/STS)
of additional peculiarities in the local tunneling conductivity
caused by the presence of low-dimensional structures - Ge ad-atoms
and domain wall on the Ge(111) surface. We also proposed
theoretical model to explain the physical reason of observed
peculiarities formation. We consider such systems to be a good
candidates for charge and spin configurations formation by means of
STM/STS technique.
