Scanning tunnelling microscopy has been used to investigate cerium-induced reconstructions on Si(1 1 1). Room temperature deposition of submonolayers of Ce is reactive and produces an intricate two layer silicide structure: a root7 x root7 phase on top of a 2root3 x 2root3 reconstruction, co-existing with the bare Si(1 1 1)-7x7 surface. Annealing the submonolayer-covered surface at 600degreesC generates a one-dimensional (5x2) structure comprising both Cc and Si adatoms. This structure coexists with the bare 7x7 and a 2x3 structure with cerium adatoms in alternating H-3 and T-4 positions.
