摘要: The adsorption of atomic hydrogen has been studied on clean and potassium modified Cu(110) Cu(100) surfaces. Two induced states in the valence band have found surface, an α state receding subsurface a β surface crystal. Upon annealing, both diffuses to desorbs at 330 K, into bulk. states, αK βK, also observed surfaces, with assigned potassium-hydrogen bond βK Cu–hydrogen bond. is significantly more reactive than surface.
