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 adatoms and domain wall on the Ge(111) surface. We also proposed a theoretical model to explain the physical reason for the formation of the observed peculiarities...
We present the results of numerical modeling of the electronic properties of the Ge(111)-(2 × 1) surface in the vicinity of a P donor impurity atom near the surface. We have shown that, in spite of well-established bulk donor impurity energy level position at the very bottom of the conduction band, the surface donor impurity might produce an energy level below the Fermi energy, depending on impurity...
