摘要：

Multi-atomic chloride layers are prepared on the clean Cu(100) surface by exposure to Cl-2 at 160 K at pressures of the order of 10(-3) Pa. The layer stoichiometry determined by XPS measurements corresponds to CuCl. Bringing the sample to room temperature, the layer undergoes a structural transformation where thicker islands are formed, while a fraction of the substrate surface becomes free. Exposure to radiation in the soft X-rays domain causes the photoreduction of the chloride layer and the formation of metallic copper. This metallic copper is located near or over the surface of the chloride.
