Structures of two kinds of wide strands with different height formed on nonstoichiometric TiO 2-x (110) surfaces are discussed based on atom-resolved STM images. Bright strands, which form linked (1x2) structure with single links and cross-links, consist of double strands of Ti 2 O 3 added rows. A structural model of the linked (1x2) structure as well as its formation...
A (3x3)R30 o C-terminated structure on Mo 2 C(0001) was observed by scanning tunneling microscopy. The structure was observed as a honeycomb structure with dark depressions corresponding to C atoms which make up the (3x3)R30 o lattice. High resolution imaging was possible at low tunneling resistance less than 1MΩ. Each C atom appears as a shallow sombrero protrusion predicted...
