Functionalization of III/V semiconductor surfaces with small organic molecules — •Patrick Vogt — Institut für Festkörperphysik, TU Berlin, Hardenbergstr. 36, 10623 Berlin; Germany.

Hybrid materials consisting of interfaces between organic layers and solid semiconductors form the basis for novel applications in sensing, biophysics and nanotechnology. The understanding of the fundamental properties that determine the interaction between organic materials and semiconductor surfaces, however, is still insufficient. This presentation summarizes our current understanding of the functionalization of differently reconstructed, carefully prepared GaAs, InP and GaP (001) surfaces with organic reagents. The functionalization is characterized by x-ray photoelectron spectroscopy, scanning tunneling microscopy, and by reflectance anisotropy spectroscopy in a spectral range between 1.5 and 5 eV.
