Zusammenfassung: 
The Au(110) surface is studied by scanning tunneling microscopy (STM) and reflection high energy electron diffraction (RHEED). The surface is rapidly cooled from above the order-disorder transition temperature of T-c = 650 K to room temperature. The STM reveals some details of the disordered state, i.e. a preference of [110] chains of varying lengths as the most obvious short range structural elements. The first long range order structural features are (1 x 3) rather than (1 x 2) islands. The (1 x 2) structure needs some energy input to be formed. The RHEED analysis is done while the target is heated in the range from room temperature to above T-c. The RHEED experiments give information about the disordered state, as well as the annealing and the order-disorder phase transition.
