Abstract
Three different methods have been applied to produce the p(4 x 1)S str ucture on Ni(110): A simple annealing of the p(3 x 2)S phase, exposure to H2S at elevated temperature, and, finally, formation via reaction of H2S With Ni(110)-p(2 x 1)O. The resulting phases are characterized, and the observation of completely new p(7 x 1) and p(11 x 1) structur es is reported. A p(4 x 1)S model is presented which is consistent wit h the STM results.
