The electronic properties of single P- and B-dopants at the cleaved Si(1 1 1) surface of Czochralski-grown single crystals are investigated by scanning tunneling microscopy (STM) and spectroscopy at room temperature. Both types of dopants (donors or

The (111) surface of P-doped Si obtained by cleaving in ultrahigh vacuum has been investigated by means of scanning tunneling microscopy at room temperature for samples with dopant concentrations below and above the metal-insulator transition. Domain

Scanning tunneling microscopy images of ultrathin Gd films on Y(0001) show a strong chemical contrast depending on the tunneling voltage. For small voltages the tunneling spectra for Gd reveal pronounced features which are attributed to occupied and

We report on the individual observation of substitutional P donors on the reconstructed Si (111) 2 × 1 surface by means of scanning tunneling microscopy and tunneling spectroscopy. Depending on the scanning voltage, the dopants give rise to differen

Superconducting properties of multilayers consisting of alternating Nb and Cu layers with a fractal stacking sequence have been investigated. Dimensional crossover is observed in the temperature dependence of the parallel critical magnetic field Bc2
