The interaction of Br 2 with Cu(100) was characterized using temperature-programmed desorption (TPD) and low-energy electron diffraction (LEED). Initial exposure to Br 2 resulted in the formation of a c(2 2) LEED pattern and CuBr desorption peaks at 870 and 1000 K. These desorption peaks saturated at a dose of approximately 5 L and were attributed to Br 2 chemisorption....
The adsorption, reaction and surface diffusion of chlorine on Cu(111) has been studied in the temperature range 110 to 900 K using low energy electron diffraction, Auger electron spectroscopy (AES), temperature programmed thermal desorption and electron stimulated desorption. Chlorine adsorbs at 310 K to form a series of surface structures for increasing coverage, (√3 √3)R30°→(6 √3 6√3)R30°, all...
