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.
