Audiffren, M.; Traimon, P.; Bardon, J.; Drechsler, M. A study of atom zigzag chains on the surface of tungsten Journal Article 1978 Surface Science Surf. Sci. 75 4 751-760 surface structure; Field Ion Microscopy Nishigaki and Nakamura have observed zigzag chains on the central (011) face of tungsten after field evaporation at T #62; 140 K. In this paper, a study of the formation, disappearance and structure of such chains is described. Tungsten tips of small radii down to 60 Ã were used. Chains of 3 to 9 spots, that are clearly visible, are found even at 90 K. Four different structure models of the zigzag chains are discussed, including the multibranch model proposed by the Japanese authors. The interpretation of our experimental results shows fairly clearly that the real zigzag chain structure is a special non-dense structure. It must be formed by a local displacement of the tungsten adatoms in the field. Without the field, a zigzag chain is transformed into a two-dimensional cluster of the nearest neighbour atom by a small increase in temperature. If the field is reintroduced, the cluster can revert to the initial zigzag structure. The zigzag structure is interpreted as being caused by forces of repulsion between the atom dipoles. no 8848

Current, Michael I.; Seidman, David N. Sputtering of tungsten: a direct view of a near surface depleted zone created by a single 30 keV63 Cu+ projectile Journal Article 1980 Nuclear Instruments and Methods 170 1-3 377-381 The vacancy structure of near-surface depleted zone (DZ), created by a single 30 keV 63Cu+ ion in a tungsten field-ion microscope (FIM) specimen, was determined with atomic resolution. Both the irradiation and pulse field-evaporation experiments were performed in situ at less, approximate11 K, so that the observed vacancy structure was unaltered by the long-range migration of self-interstitial atoms. The following basic physical quantities were measured: (1) the number of vacancies; (2) the dimensions; (3) the vacancy concentration; (4) the distribution of first-nearest-neighbor vacancy clusters; and (5) the radial-distribution function for the vacancies out to ninth-nearest neighbor. The values of these quantitieswere shown to be similar for both the near-surface DZ and DZs created in the bulk of the same specimen by 30 keV 63Cu+ projectiles. no 8862
