摘要：

Tl submonolayers were deposited from an aqueous electrolyte on a Cu(111) surface. The electrodes were studied inside and outside the electrolyte with standing X-ray wave fields. These measurements allow to determine the fraction and the position of Tl atoms which occupy adsorption sites coherently relative to the bulk diffraction planes. The results show that the method can be applied to ex-situ as well as in-situ structure studies of the solid/liquid interface. The influence of oxygen on immersed and emersed Cu electrodes is discussed in detail.
