✦ Synopsis

Dedicated to Professor Dr. Wolfgang Richter on the occasion of his 60th birthday

The energetics and atomic structure of the P-rich GaP(001) surface are studied by first-principles total-energy calculations. For (2 Â 2) reconstructed surfaces we predict the formation of a P bilayer, which is semiconducting due the formation of inequivalent dimers.

In this study soft X-ray photoemission spectroscopy (SXPS) and scanning tunneling microscopy (STM) were used to investigate the microscopic structure of the P-rich so-called (2Â1) reconstruction of InP(001). The samples were homoepitaxially grown in a commercial MOVPE reactor, transferred to ultra h
