Outline of Final Research Achievements

Phosphorous-silicon heterodimer incorporated in the Si(100) surface was investigated by means of scanning tunneling microscopy (STM) and density functional theory (DFT). A comparison between experimental and simulated STM images obtained with various sample biases determined the structure of the P-Si heterodimer: The P atom is buckled down to the surface while the Si atom is buckled up to vacuum. This result rejects the previously suggested structure of the P-Si heterodimer. Scanning tunneling spectroscopy and DFT calculation revealed an intense density of state around the Fermi level and this state causes the bright feature of the P-Si heterodimer in the STM images. Furthermore, we found a candidate associated with phosphorous in an STM observation, which is predicted by DFT to bear a spin polarized charge density near the Fermi level. This will be experimentally investigated in the future.
