摘要
The room temperature deposition of Sb on to Cu(111) gives rise to two different Sb states as seen from the Sb 4d shallow core level: an adstate similar to the (root 3 x root 3)R30 degrees structure formed after annealing at 400 degrees C, and an overlayer of unreacted Sb. The unreacted Sb overlayer is rapidly dissolved into a subsurface position in the crystal during annealing, where it forms a quasistable structure which is dissolved very slowly.
