Competition between silicon, beryllium and phosphorus atoms in the formation of surface chemical compounds on (1010) Re

High-temperature joint adsorption has been studied of three different adsorbates, Si, Be, and P on the (1010 ) Re face. All three adsorbates form surface compounds with the stoichiometry ReX, where Xis Si, Be, and P. In joint adsorption, one of the adsorbates is displaced into the bulk, into the dissolved state. The processes are observed at a temperature sufficient for diffusion in the bulk, 1100-1300 K. Displacement occurs in an atom-to-atom mode, and it has a "cyclic nature": silicon displaces phosphorus, beryllium displaces silicon, and phosphorus- beryllium.
