| Résumé | It is shown that an air-stable Ge(111) surface can be made by wet chemical HCl treatment in ambient atmosphere. X-ray photoelectron spectroscopy (XPS) and photon electrical field polarization-dependent Cl K-edge x-ray absorption spectroscopy (XANES) were used to study the chemical structure and the physical orientation of chemisorbed Cl. It is found that Cl forms a monovalent bond with the Ge(111) dangling bond (DB) along <111> surface normal. The stability of HCl-treated Ge(111) is attributed to the surface DBs being terminated by monochloride. Thermodynamics are found to be the governing force in the Ge舑HCl reaction processes. |
