Step-induced short range order on Si(100) reconstructed surface

K.Kakitani, R.Sakagami, T.Kawamura, Y.Yagi, A.Yoshimori

Two kinds of interaction model are proposed to the asymmetric dimer model of the Si(100) reconstructed surface. One is the short range interaction model, and the other is the one including the longer range electric dipolar interaction. Short range order structures at step edges are examined for the two kinds of interaction model, and some differences are found. An attempt is made to compare the results with the STM images.
