Abstract
We present the results of a high-resolution x-ray scattering study of the thermal roughening of Ag(110). Using scattering from the bulk forbidden (11¯0) surface peak as a probe, we obtain direct information about thermal variations in the height-height correlation function. Specifically, we find that the surface undergoes a roughening transition at =(450±25)°C. Above , the rough phase is characterized by logarithmically divergent height fluctuations.
